D9VK and Skyrim Legendary Edition: Artefacts with MSAA enabled

[varris1]

Describe the bug After I enabled 8x MSAA, artefacts appeared ingame. RADV_PERFTEST=llvm didn't show that behavior

System information:

• GPU: AMD RX 590 (Polaris)
• ACO version: master branch, commit: 5c6077221dd0718f09c12fc1b1a6f65595416288

Additional context I used Wine & D9VK.

it works with https://github.com/daniel-schuermann/mesa/tree/master_old_2019_07_12 I'll check back, when I found out what broke.

Actually, it didn't work. The old branch just misses a feature so that some shadows aren't rendered at all. We'll keep you posted.

Actually, I think both images are wrong and LLVM just got lucky that it doesn't look so terrible.

Can you confirm that this is the expected output?

So is this really Skyrim Legendary Edition + D9VK, or is this Skyrim Special Edition with DXVK? I see a DXVK HUD on there?

nvm, looks like D9VK also has the same HUD.

FWIW I cannot reproduce this with upstream radv & a vega.

Here is a screenshot of Gallium Nine. In hindsight the LLVM image doesn't seem to be correct either.

I will ask @joshua-ashton to take a look at it since it could just be an issue with D9VK itself.

Did you try with PROTON_USE_D9VK=1 ?If I do this, I only get abnormal program termination... but I start to get the impression that this might be a D9VK bug and not the driver.

'Twas an issue on my end that was not easily apparent visually with LLVM.
