Ppsspp: [Vulkan] Burnout Dominator - Graphical issue

[leopard20]

The cars and the tracks are not rendering properly. It's very similar to this issue: https://github.com/hrydgard/ppsspp/issues/10655

Tested v1.7.1-141, v1.7.1 and v1.6.3 and got the same result on all three. OGL works fine.
It's weird though. I can swear I used to play this game flawlessly before. It seems to have happened after updating my OS. So chances are it's a driver bug. Or maybe it's caused by Depth Clamping, which wasn't available on my previous driver.
Can someone else test and verify this plz?

Device: Mi 5s plus, Android 8.0, Vulkan backend.

It's probably the recent changes to buffer management that were made to allow speedups in some games. It's clear that something was overlooked. Thanks for reporting!

[leopard20]

Thanks for reporting!

You're welcome!
BTW, I tested version 1.5.4 and that one worked fine. So I guess you're right!

at burnout legends too had this issue also when sun approached framerate getting crawl

Tested both Burnout games, no issues here (Windows 10 x64 October Update and Nvidia GPU):

@ppmeis And this is the Vulkan backend?

@ppmeis And this is the Vulkan backend?

Yes it is.

Maybe this is related to the #10421 issue and Adreno specific?

[crazyrexz]

confirmed i using adreno and vulkan too, snapdragon 625, 64bit. so its adreno only, or maybe another android gpu got this issue too? like mali powervr etc

[hrydgard]

Still an issue?

[leopard20]

Yeah. Nothing has changed.

[hrydgard]

More screenshots in the linked duplicate. Seems like another fun Adreno bug to investigate.

Could you try exporting a GE frame dump? These help a lot.

See here for instructions - it's not hard and works on Android too:

You can zip that and then drag and drop it into a reply here.

@leopard20 Can you also check the Game ID of your game? (hold press the icon on the game selection screen, it's after the name).

[leopard20]

@hrydgard
ULUS10236

@unknownbrackets
Is there something wrong with the remote debugger? It keeps saying not connected.

[crazyrexz]

hi, it still slow down at sun area on me, im on latest build github right now. using opengl or vulkan same result. both legends and dominator

[leopard20]

@crazyrexz Turn off block transfer simulation.

[crazyrexz]

@leopard20 oh is it thanks! yeah finally can play burnout series with stable, i dont mind the annoying boxed shadowed sun, as long as game not hurt. oh a question, by default the vertex cache is checked, is it matter with performance if unchecked? im using vulkan.

btw thanks devs @hrydgard and other people whom fix this.

[leopard20]

@crazyrexz Vertex cache doesn't affect the performance much (it nearly has no effect at all) thanks to some optimizations. If you're using Vulkan, you can turn it off safely without any performance hit.

[hrydgard]

That's not entirely true, there are some edge cases where vertex cache helps by a few percent - but yeah, not like before.
