SUMMARY Regression performance in benchmarks (Shadow of the Tomb Raider native Linux and Cyberpunk 77 via proton) while using Wayland: around 8 to 10% after upgrading to plasma 6.1. Those 2 benchs were on par with X11 on Plasma 6.0, now they are 10% slower... STEPS TO REPRODUCE 1. Bench SOTB on Wayland Plasma 6.1: ~275 fps 2. Bench SOTB on Wayland Plasma 6.0: ~300 fps 3. Bench SOTB on x11 Plasma 6.1: ~300 fps STEPS EXECUTED TO MITIGATE THE PERFORMANCE LOSS: 1. Disabled Triple buffering via env variable ( KWIN_DRM_DISABLE_TRIPLE_BUFFERING=1 ) and reboot => Performance issue still here 2. Disabled screen tearing in Display settings => Performance issue still here 3. Disabled ICC color settings => Performance issue still here 4. Switched to a different kernel version => Performance issue still here SOFTWARE/OS VERSION Linux/KDE Plasma: Arch Linux KDE Plasma Version: 6.1.0 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 ADDITIONAL INFORMATION CPU 5950x GPU RTX 4090 Nvidia Beta 555 Drivers 555.52.04 Kernel 6.9.5-1-cachyos-bore
Can you observe the same with NVidia driver 550? This sounds like a regression caused by explicit sync
(In reply to Zamundaaa from comment #1) > Can you observe the same with NVidia driver 550? This sounds like a > regression caused by explicit sync Good call. I should have written in the bug report that I used a patched version of kwin which included the explicit sync patch.
