CUDA works fine here, in all honesty it’s never given me any problems. NVENC works fine, DLSS1, DLSS2, and DLSS3 all work fine, RTX runs at acceptable FPS compared to AMD under Linux - and NVIDIA Reflex is supported as of VKD3D-Proton 2.12 and DXVK-NVAPI 0.7.
On top of that, FSR is also fully supported - as is HDMI 2.1.
I only use Firefox, and hardware web rendering works fine. Hardware video acceleration isn’t working yet, but running back to back tests at 1080p with hardware video decoding under VLC, the difference between hardware video decoding and CPU rendering is about 5% CPU usage on average running a desktop PC with adequate power supply/cooling capacity as opposed to a laptop with limited power supply/cooling capacity.
The only problem with Wayland under KDE 6 is the lack of any form of sync, but explicit sync has ‘finally’ been merged, and should be supported under the 555 branch of drivers. Once explicit sync is supported, I really have few Wayland issues left to complain about.
Overall, I really don’t experience any showstopper issues that have me wanting for Windows in the slightest.
