renderdoc capture part 6/6
The issue is still present with mesa-git 19.2.0_devel.111622.f8f222ea364 llvm-libs-git 9.0.0_r318552.0d20969deaf The game now works with the latest open amdvlk driver. Like amdgpu-pro, it doesn't show this issue. How does it look with AMDVLK? With amdvlk, the shadows look correct (no weird bright spots that wander with the camera). There is an issue with amdvlk though related to the game's effect of the level's borders, but that seems totally unrelated to any shadow issues, I'd say. A screenshot with amdvlk without the artifacts: https://abload.de/img/screenshot_20190611_2elj3e.png The issue is most prominent with radv when the sun is shining. The artifacts with RADV are only with the minimap right? After turning off the minimap in the game's options, the "shadowmap holes" are still there with radv (look a bit like drops in this screenshot): https://abload.de/img/screenshot_20190611_28wkhv.png I don't see what's wrong? I've highlighted the artifacts: https://abload.de/img/screenshot_20190611_2jqkx1.png It looks quite worse in motion, as these bright spots shift their shape, wander etc. Oh okay, I see :-) Created attachment 144874 [details]
same corruption in Odyssey
I've added a screenshot showing the same corruption in Assassin's Creed: Odyssey (no issues with amdvlk). That means that likely also the titles "Syndicate" and "Origins" of that game series are affected as well, which sums up to at least four games with that corruption. Someone here reports of the issue in Origins, but only with ACO: https://github.com/daniel-schuermann/mesa/issues/105 Perhaps I was a bit too quick judging it was the same issue on Odyssey as in Unity, will recheck. So I rechecked with recent ACO build which fixes AC: Origins and Odyssey, and it indeed also fixes Unity. But the issue in Unity is still there when using LLVM. So, afterall, it seems it is a bug in LLVM and not radv (hence closing). (In reply to tempel.julian from comment #19) > But the issue in Unity is still there when using LLVM. So, afterall, it > seems it is a bug in LLVM and not radv (hence closing). It's too early too conclude that. RADV could be feeding something bad to LLVM. AMDVLK also uses LLVM, after all. |
