Proton: Project Cars 2 (378860)

[leillo1975]

It installs prerequisites and it executes showing the first screens and then it get blocked.
With wine the game runs in menus, but fails when load a race.

Hello @leillo1975, please add PROTON_LOG=1 %command% to the game's launch options and drag and drop the generated $HOME/steam-$APPID.log into the comment box.

Today, I started again the game with Proton 3.7.6Beta and now it works in menus, but when I try to start a a race it crashes during loading. This is my last log:

steam-378860.log

The problem is the same with 3.7.3

[ah-]

The loading crash is in the process of being fixed, follow https://github.com/doitsujin/dxvk/issues/641 for details. Runs perfectly now for me, hopefully everything will be out in the near future.

[leillo1975]

Thanks a lot, @ah- it's very complicated for me compiling, but I see that @doitsujin will take care of this problem. Can you share the file that you compiled to replace PCars2.exe? Perhaps in a close future we can enjoy this fantastic game on Linux without this fixes.
Only one thing, I see that you are quite adept at fixing problems. You I don't have idea if you own Project Cars 1. It works perfect with proton, even with Force Feedback in my G27, but I have an notice when the game try to save the profile and the progress.
I opened an issue about this P.Cars 1 problem:
https://github.com/ValveSoftware/Proton/issues/244

[ah-]

Haha, if you can't wait then place the two dlls in the attachment in $HOME/.steam/steam/steamapps/common/Proton 3.7/dist/lib64/wine/dxvk and it should run.

pcars.zip

Sorry, don't have Project Cars 1, and not quite enough time to go and debug that. Just really wanted to get Project Cars 2 working :)

[leillo1975]

@ah- You are my man!!! It works. Thanks a lot
The game is playable now!
There are a problem, it has nothing to do with this, it's a proton problem. I can use my Logitech G27 wheel, calibrate it (pedals included), but the force feedback don't work (in PCars1 works)

[whizse]

You can use WINEDEBUG with +dinput to log what FF effects the game is trying to use. On my system I get a lot of
"Effect gain requested but no effect gain functionality present." and
"Sample period requested but no sample period functionality present." and none of those effects are implemented in the driver. I sadly think the lack of force feedback in the game is just incomplete drivers.

[leillo1975]

It's a pity. There are a lot of games I suspect that have the same problem... Great games like rfactor2 or Automobilista. At least Assetto Corsa, and AC Competizione works well

[leillo1975]

I don't have idea of developing, debuggin and this kind of things, but Maybe this project has something to do with the subject ....
https://steamcommunity.com/groups/linuxff/discussions/0/405692224235574471/

I think that Valve could take a look of this problems with wheels on Linux. A lot of racing games could be benefit by a more complete drivers

[kisak-valve]

Hello @mimattr, the request to switch this to a white list request is denied because a demo counts as an independent test case for Proton and is not a reliable indicator of compatibility with the full game version.
Additionally, the tested Proton version must be an unmodified version from Steam.

[mimattr]

Appreciate the explanation @kisak-valve and apologies for any confusion, a separate ticket has now been created (#1603)

As an aside it's great to see a title with planned native SteamOS support finally working on Linux! :wink:

[leillo1975]

Please Valve, fix feedback in wheels

[leillo1975]

FIXED!!!!!!!!!!!!!!!!!!!!

It works perfect, with Force Feedback in my G27 Wheel! Thanks a lot, Valve! :)))

[whizse]

@leillo1975 That's very interesting! The demo (at least for me) still doesn't work with FF. Was it a game update or Proton update that fixed it? If possible, could you try the demo as well?

[leillo1975]

There is an beta update of proton (3.7.7 Beta). With this version the game now runs without fixes and with Force Feedback. Play Online make the game crash.
About F.Feedback: if you make an Alt-Tab, this feature get lost

[leillo1975]

One question, two days ago the game was updated, and now I don't have force feedback. Can you say me if yoy have the same issue?

Thanks

[madbad]

I'm experiencing the same "Missing Force Feedback" issue after the game update, it worked before the update.

[ah-]

Still works for me, I do have working FF via https://github.com/atar-axis/xpadneo.

[leillo1975]

@ah- what controller you use?

[ah-]

It's a recent Xbox controller, not quite sure what the exact model is.

[leillo1975]

Our problem is with Logitech Wheels.

[madbad]

Do anyone else also get stuck at 75% loading when trying to get into a race with AI ?

[leillo1975]

After the last Proton beta (3.16-4Beta) PCars2 works online and don't crash to desktop. Unfortunately, after game's update one month ago , Force Feedback stills missing. Please Valve, take a look on this. It's a great game

With the previus version Force Feedback works fine. I think that Linux users should pressure PCars2 developers to make the game work again with a new patch. I made a thread on P.Cars forum to ask for this. Please show your support:

Anyway I think valve can solve the issue through proton, the developers of PC2 are not going to make changes in the game because of a linux issue...

Great, this solved the problem for me.

Now the only issue remaining is the missing ForceFeedback (I will give a try on downloading the old pCars2 version since it was working with that).

[seibacks]

I can confirm it after buy the full game:

ForceFeedback working on Project cars 2 - 1.7.0.0

ForceFeedback NOT working on Project cars 2 - 1.7.1.0

[xpander69]

Same issue here. FFB doesn't work
log reveals that:

107214.718:002f:006d:err:dinput:effect_Download SDL_HapticNewEffect failed (Effect type 128): Haptic: Effect not supported by haptic device.
107214.734:002f:006d:err:dinput:effect_Download SDL_HapticNewEffect failed (Effect type 128): Haptic: Effect not supported by haptic device.

i tried to search what this effect type 128 is, but didnt find anything. I guess i have to downgrade to older version also. The Game works superbly other than that. Just need my FFB

edit: ok managed to downgrade to 2 months old version. FFB works great. What an enjoyable experience.
However like mentioned already, alt+tab will kill FFB again, have to restart the game.

the same Haptic Effect type 128 errors are still on the log, so that doesnt break the FFB on the newer version i guess, theres something else.

[seibacks]

There's a huge difference between playing with and without Force Feedback, for me is a mandatory feature...

I found this (related with dirt 4, but also with FFB): https://github.com/ValveSoftware/Proton/issues/992#issuecomment-441951034

Apparently in wine 3.20 it works, but it doesn't explain why is working with the previous version of PC2 and not with the latest... maybe is working with a specific implementation of FFB??? really weird...

[leillo1975]

We'll have to wait for Proton to upgrade to version 3.20.

[wleoncio]

I can confirm it after buy the full game:

ForceFeedback working on Project cars 2 - 1.7.0.0

ForceFeedback NOT working on Project cars 2 - 1.7.1.0

Came here to second this. On the other hand, online works with 1.7.1.0 and breaks with 1.7.0.0. I'd rather have FFB, so I'm keeping the game downgraded, but it sucks having to choose. Moreover, 1.7.0.0 crahes sometimes, either before the start screen or when starting an event. I am using Ubuntu 18.04, Nvidia GTX 650 Ti BOOST with proprietary drivers and a Logitech Driving Force GT wheel.

Symptoms

Photo mode does not work

Reproduction

1. Start the game and get on track (game mode doesn't matter)
2. Pause the game and choose "photo mode"
3. Try to take a photo by pressing "take photo" or pressing the left mouse button

(alternatively)

1. Start the game and go to "private testing", then "vehicle select"
2. Choose "Showroom" and "Photo mode"
3. Try to take a photo by pressing "take photo" or pressing the left mouse button

Instead of taking the photo, the game temporarily freezes, with the shutter sound repeating indefinitely. Pressing "Esc" goes back to "photo mode" and game can be played normally. Photo is not taken, as it won't show up in "My Profile / Images" and the "Snap snap snap" achievement for taking a photo doesn't pop up.

I've also tried with nvidia driver 415.25 and game version 1.7.1 (OP using 1.7.0) with same results.

[Kreyren]

any ETA on force feedback?

[viggy96]

I haven't been able to launch the game recently, possibly due to a game update, though not sure of the cause. I'm running Ubuntu, Radeon VII GPU, and Padoka Stable Mesa. I've been able to run this game before on my setup.

[leillo1975]

Force Feedback stills not working with the last version of Proton (4.2)

[xpander69]

Yeah, confirming, no go with 4.2 for me either and no go with custom proton-tkg 4.4.r8 either. Something with native steam client killing the FFB? as the FFB works fine with regular wine 4.1 to 4.4

edit: Whoops wrong post. I was thinking its Dirt Rally 2.0 issue. Don't mind me. But probably both have similar issue anyway.

yes i had (with wine-staging 4.2). but i haven't tested now, i was posting in the wrong place, thinking it was Dirt Rally 2.0

Same here, still no FFB with proton 4.2 on the latest version of the game.

Still works on the old version of the game.

[pipnina]

I just got PCars2 and can confirm that my Logitech G29 works with FFB in PCars1, but PCars2 it is broken. Though I have not noticed any other issues in the short time I've played.
I tried to use the steam console (by typing steam://open/console/ into my web browser) and downloading the older version, but it just says that it is downloading the package without queuing an actual download. Am I maybe doing something wrong?

According to the previously-mentioned source as well as my own experience, "[y]ou won't see any indication of [download] progress, but you can tell it's downloading by looking at the network usage on your downloads page". Do you see any download activity? Other than that and the occasional console message, you won't see any other indication that the game is downloading. There's no population of a download queue, but the download should be triggered.

[pipnina]

I've just looked in the game's files, and noticed dlls relating to Easy Anti-Cheat. Is there any risk of being banned in this game if I try to join an online lobby and the anti-cheat flips out? I've heard that EAC behaves very badly with WINE/Proton and would rather work on the safe side of things.

[wardbox]

The force feedback issue persists. I'm downgrading now to an old version to see if that works as well. Confirmed that Project Cars 1 force feedback works fine.

Using G920.

Update: Downgrade to recommended version of Project Cars 2 does return force feedback. Unfortunately, it's still really light even on maximum settings. In Project Cars 1 it is far more pronounced.

[viggy96]

@kisak-valve Here's a crash log for Project Cars 2. This game used to run with Proton, I don't know what happened.
steam-378860.log

[ah-]

Still runs fine for me @viggy96

[pipnina]

Same. Runs fine for me as well @viggy96 . Maybe try re-downloading or making sure your system is up to date (and rebooting)?

[viggy96]

@ah- @pipnina @kisak-valve Reinstalling the game has no effect. However, I can run the game with wine steam via Lutris. The error appears to be something to do with the version of libsdl2 that Steam is loading.

[viggy96]

Same issue when using Proton 4.2-3. I've tried installing a backport libSDL2, version 2.0.9, from ppa:cybermax-dexter/sdl2-backport, but it didn't help.

Symptoms

Thrustmaster Ferrari FGT 3in1 is not recognized correctly

Reproduction

Plug the wheel, start the game, start a race. Depending of the controller options in steam, the wheel, pedal or both are not working. The wheel works well in native game like F1 2017 and perfectly recognized by the system (all axis and buttons working in the KDE controller test). Already tried calibration and controller management options in steam. No option gives acceptable behaviour (pedals, wheel or both have no action in game)

[viggy96]

@kisak-valve I think I've figured it out another bit of the issue I'm having. My Corsair mouse is being recognised by Steam as some sort of controller, you can see in the terminal output:

Local Device Found
  type: 1b1c 1b2e
  path: sdl://1
  serial_number:  - 0
  Manufacturer:

When I don't have my Corsair gaming mouse plugged in, and just use a regular mouse, this game runs fine. It appears that we may need to blacklist some devices from being detected as "controllers" and being passed to the game as such.

[necrophcodr]

I can confirm that the FFB issue with latest version of Proton available in Steam and latest version of Project Cars 2 as of writing.

I've tried downgrading the game, however unfortunately that results in either the game hanging forever when loading a stage, or crashing to desktop entirely, both without any messages or log information to speak of, that differ from that of playing the latest version of the game without FFB.

This is with a Logitech G29 on Ubuntu 18.10.

with Proton 4.11-1 the FFB problem persists.

steam-378860.log

[petersmi]

I installed the demo last night with Proton 4.2-9, driving with a Logitech G920. I was getting spring centering in the menus, but no FFB during play. Checked out the hid debugging info from the kernel driver, and noticed that it was sending good force data, but the direction parameter was causing it to zero out. I hacked out the angle calc in the driver, and FFB worked fine after that. Tried the full game, and it's been working great(after setting nofile limit super high to get rid of hangs)

@leillo1975, is it recognizing your wheel at all? I wasn't able to get a reliable steam-*.log when I was initially looking at this because of the eventfd issue and my nofile limit set too low, but when I was trying to get ACC to work, it had a lot more wheel info in the log than I see in yours.

The drivers for these wheels do seem rather poor, at least for the G920. It looks like there was a fair bit of work recently on the hid-logitech-hidpp module, but it breaks FFB entirely on my wheel after kernel 5.2, not recognizing it as an HID++ device at all anymore.

[saipathuri]

@petersmi how did you change the angle calculation in the driver?

[petersmi]

in the hidpp_ff_upload_effect function in drivers/hid/hid-logitech-hidpp.c
under the FF_CONSTANT case
I commented out the line:
force = (effect->u.constant.level * fixp_sin16((effect->direction * 360) >> 16)) >> 15;
and replaced it with
force = force = effect->u.constant.level;
The direction value I get from PC2 was getting zero'd out by the sine. Dividing direction by 2 works as well, but then other games would get reduced force.

I'm not sure where the real 'bug' is in the chain until it gets to this point. My assumption is the windows drivers don't care about the angle for these wheels, and the games don't have to pass good values, but that's just a wild guess. So for this driver, maybe there should be a HIDPP_QUIRK_CLASS_G920 test for this angle calc like there is in a few other places in the module.

I've been meaning to check out what this guy has been working on:
https://steamcommunity.com/groups/linuxff/discussions/0/405692224235574471
since my wheel is completely borked with kernel >=5.2.0, but haven't gotten around to it yet.

VR doesn't crash for me but it's so slow that its unplayable on an AMD rx 580 with the latest valve mesa aco installed on Ubuntu 19.04 proton version 4.11-3 and the latest steam vr beta. The rest of the game works fine.

[Termuellinator]

i'm noticing that the steam client closes when exiting PC2 since the last two or three steam beta-updates. Haven't noticed it on other games. Can anybody confirm?

[StefanTT]

Force feedback is still broken on Arch with latest proton (4.11-7 ?).

VR with index works fine. Sometimes it has unusable stuttering, but after restarting Steam and the game it is fine again.

[leillo1975]

Still broken for me too. What's your wheel model?
Since a few days there are a new project to collect ffb data from the wheels and games. It's a @berarma project, like Oversteer, and it's called Ffbtools. You can find it here:
https://github.com/berarma/ffbtools

Its use is very easy, in the launch preferences of the Steam game you only have to write something like this:
/home/user/ffbtools/bin/FfbLogIoCalls.sh /dev/input/eventX /home/user/FFBLog -- %command%

[StefanTT]

I have a Logitech Driving Force GT.

Thank you for the hint with ffbtools, I found it after writing my comment. I will test it tonight or tomorrow. As the fix in ffbtools already was reported to help in Dirt 2.0 I have hopes that it helps in my case too. I will report back here.

[mkasprzak]

I have tested Project Cars 2 + ffbtools + G29 today and it does not help.

[leillo1975]

I think I found a regression (@kisak-valve ) on the last version of Proton (4.11-7) with the force feedback feature. Today I downgrade Project Cars 2 (https://github.com/ValveSoftware/Proton/issues/908#issuecomment-480472147) to the previous version before the October 2018 update.

With the last version, the ffb don't work, but downgrading to 4.2-9, 3.16-9 or 3.7.8 the feedback is back again. This problem is not only related to this game because I found that:

• Project Cars 1 ( https://github.com/ValveSoftware/Proton/issues/244 ) has the same problem, and the ffb of this game was working in previous versions.
• Wreckfest ( https://github.com/ValveSoftware/Proton/issues/758 ) lost ffb and has problems with calibration. With 4.2-9 everything runs great.
• GT Legends ( https://github.com/ValveSoftware/Proton/issues/2728 ) only has ffb when you crash your car, but with 4.11-7 this effect is lost
• RACE 07 ( https://github.com/ValveSoftware/Proton/issues/1212 ) has the same problem that GT Legends (same developer)

Please, take a look on this

Force feedback is still disabled when using the fix script.
Switching to Proton 4.2-9 does not help.

[leillo1975]

Ffb only works on the downgraded version of Pcars2

[mkasprzak]

I confirm what @leillo1975 discovered. Downgrade of Project Cars 2 (steam console: download_depot 378860 378861 4000032546361002812) + downgrade of Proton to version 4.2-9 fixes/enables FFB on G29.

[berarma]

I've found what the problem is with the latest versions of the game. The FFB effects sent have a direction vector. The Logitech driver scales the level of the effect using the horizontal component of that vector and ignoring the vertical component. The latest versions of the game send effects with a vector pointing down (180º), thus with a null horizontal component. This cancels the effect.

I'm not sure where the problem is. It seems like the direction vector was originally implemented with joysticks in mind, and it has been implemented for wheels in a way that Proton or maybe the games were not expecting. We should maybe look at what Proton is doing, or maybe review what this direction vector should be doing. There's no API documentation that I know of explaining how this direction vector should work for wheels.

I've implemented a workaround to show how FFB starts working when the direction vector is changed from 180º to 90º. You can find it at https://gihub.com/berarma/ffbtools. The command to launch the game should be (changing the device path if needed):

ffbwrap --direction-fix /dev/input/by-id/usb-Logitech_G29_Driving_Force_Racing_Wheel-event-joystick -- %command%

This is not a proper fix. We need to understand what's wrong and fix it either in Proton or the kernel driver.

[leillo1975]

I can confirm that last version of Project Cars 2 with Proton 4.2-9 works with the @berarma fix, and is really great. Now is not needed to downgrade the game. Thanks a lot again. You fixed Dirt Rally 2 some days ago, and now this game.

[berarma]

@petersmi I just read your comment. We've reached the same conclusion and implemented a similar workaround. There seems to be no one that is aware of these problems. Someone will have to step forward and do the work to document the API and fix bugs. You can join us if you want to. See my comment above.

[StefanTT]

Yep, downgrade, proton 4.2-9, and the FfbFixUpdate.sh are required to get consistent force feedback.

[mkasprzak]

I updated PC 2 to newest version and tried to use @berarma ffbwrap to fix FFB (still using Proton 4.2-9), does not work for me.
Code location:
/home/mkasprza/Projects/ffbtools/
Build cmd:
~/Projects/ffbtools$ make -j6
My "SET LAUNCH OPTIONS...": /home/mkasprza/Projects/ffbtools/bin/ffbwrap --direction-fix /dev/input/by-id/usb-Logitech_G29_Driving_Force_Racing_Wheel-event-joystick -- %command%
I'm missing something ?

[leillo1975]

I don't see nothing strange. I suppose that your wheel is a G29...

What's the terminal output when you compile ffbtools?

[mkasprzak]

I was missing gcc-multilib and libffbwrapper-i386.so failed to build. Everything works now :D

[vhakulinen]

ffbtools makes force feedback work on pc2 here too (with proton 4.2-9).

[leillo1975]

New version of Proton (4.11-8) stills breaking Force Feedback in a lot of racing games. With ffbtools don't work.
Other games like:
-Project Cars 1
-RACE 07
-GT Legends

https://github.com/ValveSoftware/Proton/issues/3194

[nelg]

I can also confirm that compiling @berarma's fix and setting ffbwrap --direction-fix /dev/input/by-id/usb-Logitech_G29_Driving_Force_Racing_Wheel-event-joystick -- %command% in the launch options made it work for me.

[OkropNick]

@berarma Thank you, thank you, and once again thanks! :) I can confirm, that your fix is working with Project Cars 2 on Ubuntu 18.04 with Proton 4.11.9. I am using Logitech_Driving_Force_Pro :+1:

[SilverLuke]

I have a problem with my G29 using Proton 4.11.9 and the @berarma's fix.
The force feedback works good, but the "rev lights" on the steering wheel don't work.
I can turn on the lights using echo 1 > /sys/bus/hid/drivers/logitech/<id>/leds/<id>::RPM<number 1-5>/brightness, but when I play the lights don't work.

[berarma]

@SilverLuke There's no way to make the leds work. It's not implemented in Wine nor Proton.

[leillo1975]

With the last version of proton (4.11-10), the game has a good Force Feedback. Good Work!

Now you just have to fix it when you do Alt-Tab and go back to the game. It hangs and the screen remains black.

[wleoncio]

With the last version of proton (4.11-10), the game has a good Force Feedback. Good Work!

Wait, does this mean FFB works out-of-the-box, now? No need to keep PC2 downgraded?

[vhakulinen]

Worked for me.

Yes, absolutely (thanks @berarma )

[StefanTT]

Works fine for me with 4.11-10, the latest version of PC2, a DF-GT wheel, and the modified logitech kernel driver (from ... berama?). Did not test it with the vanilla kernel driver.

[leillo1975]

Works fine for me with 4.11-10, the latest version of PC2, a DF-GT wheel, and the modified logitech kernel driver (from ... berama?). Did not test it with the vanilla kernel driver.

I think you don't need to install the @berarma driver module for kernel for this game, but if you want to play games like rFactor2, Automobilista or RACE 07 (and more), you must use it to get Force Feedback, because this driver activates a lot of effects that are used by this games.

[vhakulinen]

PC2 has working force feedback without ffbtools or any extra kernel modules (for me at least). Running Ubuntu 18.04 (with padoka PPA).

[leillo1975]

When I said "thanks @berarma", on this occasion it was not for creating the new driver, but because he was involved in the resolution of this and another FFB issues.

[leillo1975]

I don't know if in other message of this thread this problem was posted, but if you do an Alt-Tab, the game hangs in a Black Screen.

[StefanTT]

@leillo1975: %command% -windowed -borderless

[StefanTT]

Unfortunately VR is broken for me with proton-4.11-11, it hangs /crashes when entering the car when the track is loaded.

Anybody else experienced this problem?

It worked with 4.11-10. Unfortunately I do not have this version at hands to double check, but it still works with 4.2.9. The GE builds usually fail to initialize the graphics device when selecting VR upon game start. So I am a bit lost here at the moment.

[kisak-valve]

Hello @StefanTT, please add PROTON_LOG=1 %command% to the game's launch options, reproduce the crash, and drag and drop the generated $HOME/steam-$APPID.log into the comment box.

[StefanTT]

steam-378860.log
I have added lines where the race track is being loaded and where I killed the program.

What I noticed is that SteamVR sometimes shows a popup that it has crashed. Only sometimes because most of the desktop hangs at this moment and I have to start my magic kill script to fix it.

System is 5.4.5-arch1-1, nvidia 440.44-4, SteamVR beta 1.9.15.

_Edit_: using the non-beta branch of SteamVR (which is also 1.9.15) does not make a difference
_Edit 2_: using the linux_temp branch of SteamVR (1.8.21) also does not help

[azampatti]

Good work on getting this included to the official supported branch!
I've swapped the proton to 4.11-11 and removed all the FFBWRAP commands and it's working almost perfect.

"Almost" due to one issue I'm experiencing, maybe there's a way that can be fixed or worked around.

I run PCARS2 with "borderless" option (simulating full screen) as it helps with OBS performance, but I found that every time I Alt-TAB out of the game, when I come back, FFB stops working.

Any suggestions for me to try to workaround this issue?

thanks!

Give thanks to @berarma, the creator of Oversteer, ffbtools and new-lg4ff, for help proton devs to fix the ffb.

[BUG] Project Cars 2 freezes loading into a race

Issue transferred from https://github.com/ValveSoftware/SteamVR-for-Linux/issues/325.
@kalrach posted on 2020-04-05T03:35:06:

Description:
When attempting to load into a custom race, Project Cars 2 will load into the cockpit but then freeze unable to take any additional input. The only way to exit is to hit [Alt]-[F4] or kill the application. In some instances the game causes SteamVR itself to crash with a prompt saying that the minimum SteamVR version required is SteamVR version 1.10.1.

To Reproduce:
Attempt to load any custom race in Project Cars 2 in VR mode. Once loaded in the game will render the initial cockpit view and then freeze, not being able to take any further inputs requiring user intervention to kill the application or for the game to crash and take SteamVR with it.

Additional Notes:
The game menu only shows up on the flat monitor and requires the user to control the game from the flat monitor. Attempts to control the game from SteamVR desktop view also causes the game to freeze and crash.

It works for me when I use Proton 4.2.9. However, this version requires an older version of Project Cars 2. See above in this thread for how to downgrade the game.

SteamVR desktop view does not work anywhere / anytime, AFAIK. At least for me.

I can't say nothing about VR, because I don't own a headset, but sometime ago is not needed to downgrade the game, and since Proton 4.11-10 FFB is fixed.

[StefanTT]

4.2.9 needs the downgrade, from 4.11 on you do not need it. Unfortunately pcars2 VR is broken for me too since 4.11.

When attempting to load into a custom race, Project Cars 2 will load into the cockpit but then freeze unable to take any additional input. The only way to exit is to hit [Alt]-[F4] or kill the application.

Confirmed, this behaviour is also consistent with Automobilista 2 #3748 (both using MADNESS Engine)

The game menu only shows up on the flat monitor and requires the user to control the game from the flat monitor.

Confirmed, as above and also reported on the DXVK issue tracker

Hopefully @aeikum can shed some light on this long-standing issue?

for some reason I don't have FFB in this game with new-lg4ff, same thing with automobilista 2, wine control show the effects but in the games there is nothing :x
in GRID and F1 2010 it working no problem

Which Proton version are you using? You should try with the latest.

[StefanTT]

@kisak-valve is there any chance to get a Proton 4.11-10 version from somewhere?
Because this is the last version where the game worked in VR (without downgrading the game)
Downgrading Proton with steamcmd does not work, it reports the manifests as not available.

It is still one of the best racing games in VR. I have to play the old version which tends to crash regularily between races. I would really appreciate the help (and others probably too).

You can get the source code here; it contains a README file with building instructions. I'll try that myself ASAP, can barely wait to test PC2 with opentrack! :crossed_fingers:

[StefanTT]

Thanks @wleoncio. I already tried it. Unfortunately it did not work. Building the current 5.0.x version works fine but I did not get 4.11-10 to build. Please report back - or contact me directly - if you succeed in building it.

[StefanTT]

For those who is coming here to download the old version of pcars2 to get VR running: the version is no longer available for download - this does not work anymore: download_depot 378860 378861 4000032546361002812

@wleoncio did you succeed in compiling 4.11-10 ?

@wleoncio did you succeed in compiling 4.11-10 ?

Sorry, no news on my side. I didn't try compiling yet, but I did find time to try a couple of builds from https://github.com/GloriousEggroll/proton-ge-custom. No dice.

[mimattr]

@kalrach @StefanTT Can also confirm this application still fails to launch successfully and now crashes SteamVR during the initial _"Namco Bandai"_ loading/startup screen and requires a Force Quit (Alt + F4)
