Monster Hunter World: Graphical corruption and performance hit not present with RADV_PERFTEST=llvm #92

Closed ghost closed 5 years ago

ghost commented 5 years ago

Describe the bug Monster Hunter World has severe graphical problems and performance decrease not present with RADV_PERFTEST=llvm

Screenshots ACO: aco

RADV_PERFTEST=llvm: llvm

System information:

Additional context Pretty sure I ran MHW fine with earlier versions of mesa-aco-git.

Haven't checked the latest commit, but even with e.g https://github.com/daniel-schuermann/mesa/commit/a60c307606237ddc9bbc35174a1274506f7974da and some previous commit the game was looking and performing fine, until ~30-60 minutes in where the frame rate dropped sub 1fps and amdgpu (Can make a proper bug report once I have time for it)

daniel-schuermann commented 5 years ago

Thx for the report! Could you test with RADV_PERFTEST=llvmvs and see if the problem persists (although it looks like pixel shader) ? Either way, would you be able to provide a renderdoc capture of the issue?

ghost commented 5 years ago

It does still happen with RADV_PERFTEST=llvmvs

Here is a renderdoc capture: https://void.johnnynator.dev/Monsterhunterworld-renderdoc.tar.gz

Can you confirm that this issue is fixed with b2bb91dcccff6053f1f2f223f4e00da957190421 ?

Johnnynator commented 5 years ago

Yep this fixed the issue.

How is performance after that fix?

How is performance after that fix?

Didn't do any exact measurements. Roughly in the position of OP's screenshot it is roughly 1-2 fps more with ACO (~42fps max instead of ~40fps max).

pendingchaos commented 5 years ago

ok

ghost commented 5 years ago

Also confirming it's fixed for me. Thanks genius (not sarcastic).

I am getting same fps with mesa ACO or RADV_PERFTEST=llvm, in a test spot standing in same exact location, however I'm probably CPU bound.
