--- Comment #5 from Béla Gyebrószki gyebro69@gmail.com --- Could you please perform a regression test to find out which commit is to blame? https://wiki.winehq.org/Regression_Testing
I can reproduce the performance drop between 7.0 and 8.0-rc2 on Nvidia drivers 525.47.04. Using the method described in comment #0 I'm experiencing ~35% drop in FPS in Unigine Heaven when comparing Wine-7.0 to 8.0-rc2 (Quality: Low, Resolution: 1280x720,Fullscreen: Unchecked).
OS: Arch Linux Kernel: linux-zen 6.1.1.zen1-1 CPU: Ryzen 5 5600X GPU: GTX 1660S 6 GB GPU driver: NVIDIA 525.47.04 Window Manager: XFCE 4.18 Compositor: disabled
In my case the performance drop is due to commit 7c844cd3c9c465bdeaf3d98d6da5f2f5e460e650 Also mentioned in bug #53408.
I also noticed that the performance penalty in recent Wine occurs when cpu frequency-scaling is enabled in the OS. When the cpu is set to a constant frequency, instead of dynamically changing, then current Wine 8.0-rc2 scores better in Unigine Heaven than 7.0 does.
