I lose at least 10 fps with 19.1.1 vs. 19.0 on RX 580.
19.1 (at least 168 fps):
19.1.1 (not more than 158fps):
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?
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:
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?
