I lose at least 10 fps with 19.1.1 vs. 19.0 on RX 580. 19.1 (at least 168 fps): https://abload.de/img/screenshot_20190625_16akrb.png 19.1.1 (not more than 158fps): https://abload.de/img/screenshot_20190625_1kij8n.png Performance regressions first occured in mesa-git around a week ago which is why I switched to stable 19.0. mesa-git was even worse though with ~150fps. Probably related to work regarding DCC? linux 5.1 dxvk-git both LLVM 8 & 9
Can you try to revert 410759091173fa61436ba46baeb20a79d5767849 ? Btw, 158 vs 168 is really a small diff.
It's an additional loss on top of DXVK vs. native D3D11 performance, so it sums up to something worse. :) I could bisect it to this commit: https://github.com/mesa3d/mesa/commit/0a313cc285c2939de9cac07f045b0b699bc208ca With it reverted, performance in mesa-master is normal.
Is there a chance to make CTS dEQP-VK.pipeline.depth_range_unrestricted.* pass without causing the performance regression?
This is unfortunately unchanged with latest master: ~148fps where it was ~162fps. amdvlk scores ~155fps, and with pageflipping + amdgpu.dc=0 ~160fps I can't workaround this anymore by reverting 0a313cc285c2939de9cac07f045b0b699bc208ca, as radv stopped building successfully without it.
Should be fixed by https://gitlab.freedesktop.org/mesa/mesa/merge_requests/2025
Confirmed, performance is back to >160fps. Thanks a lot, your efforts are really outstanding!
Can you please wait before closing tickets? Sending a change doesn't necessarily mean that it will be pushed/accepted. Thanks!
Of course, sorry.
Can you please pull the MR and try again? Does the performance regression is still fixed? I would say yes, just want a confirmation.
With the updated MR, performance unfortunately is worse again.
Okay, that's unfortunate but I prefer correctness vs performance. I will wait for the MR to be reviewed and let you know what happens.
