    > UPD1: I've also noticed that Horizon 6, and it's the only game that does this, _really_ doesn't like it if I have a youtube video running in the background. Stutters, FPS loss. Stop the video, the game becomes smooth. ...

    Still trying to make it work on my 2080 Ti. I've changed to CachyOS and 610.57.04 driver, but still nothing. Tried Proton 11, Experimental, proton-cachyos-11.0-20260703-slr-x86_64_v3, and nothing. With and without launch...
