Proton: Underrail (250520)

Error:

wine: Call from 0x7b43c45c to unimplemented function mscoree.dll.CorIsLatestSvc, aborting

Would like to add that it works on normal WINE Steam install.

Hello @dRaiser, this unimplemented function is already being tracked at #18. Closing as a duplicate.

Reopening this for the XNA category...

Thanks @flibitijibibo, it should be noted I closed this issue report fairly early on, before a general policy had been established for unofficially supported games.

I just tried this with Proton 4.2-3, but didn't have any luck. I've attached the proton log. I hope this is helpful.

The game launches and runs fine, but is unable to save:

328674.358:0027:0028:warn:debugstr:OutputDebugStringA "Underrail (Ouroboros) - Error - 40000 : [Timelapse Vertigo] - Failed to save game 'savegame'.

Attached is the relevant log.

Sounds like a possible Mono corlib incompatibility, Random is supposed to be Serializable:

https://docs.microsoft.com/en-us/dotnet/api/system.random

Though why Random is serializable, I don't know... usually devs set that as ignored via XmlIgnore or something along those lines.

[madewokherd]

Mono uses System.Random from corefx.

Even if we marked it as serializable, I don't think it'd be compatible with .NET, though the version from referencesource might be.

[madewokherd]

Swapping in System.Random from referencesource gets it past that exception.

[madewokherd]

Besides code formatting, attributes, and variable names, it the only difference I'm noticing between referencesource and corefx is that corefx's default constructor doesn't seed based on timer. I haven't worked with .NET serialization, but I imagine the corefx version could easily be made compatible.

Corefx has a bug for it here: https://github.com/dotnet/corefx/issues/32354

For some reason the bug discussion got caught up on the potential for serializing derived types, when the test case just uses System.Random.

[madewokherd]

Corefx isn't interested in a fix, so I changed wine-mono to use the referencesource class. It should be possible to save now (Proton 4.11-8).

Symptoms

Game launches, but when hovering your cursor over objects in game, FPS drops drastically. Massive stuttering.

[shoober420]

Heres a log using Proton 4.11-11 and NVIDIA 440.44, which still has the big FPS drop when your cursor mouses over objects in the game.
