how do you use it in the chrome then in fullscreen mode? how do you prevent when escape is being pressed that you dont get thrown out of full screen?

btw, this looks okay:

Additionally,

I've tested two browsers, Chrome and Brave from Flatpak, both having GPU Acceleration enabled, the installed RPM version of google chrome. All 3 of them yielded exactly the same result, lowering the resolution to unbearable 720 as soon as I started moving.

Unsure what is causing this, maybe my graphics card, maybe some entry missing under gpuinfo.

I'll probably give up eventually and reboot to windows when I'll want to play, or just move to boosteroid.

Thank you all for the suggestions and support :)

Is there any way to force 10 bit color support? Btw, the script for me works fine, 2k and 120 fps.

btw, this looks okay:

No it does not. "Video Decode" here, means that the feature is enabled. As I wrote, you need to have codecs listed in Video Acceleration Information

hi @kubrickfr and thank you for your feedback. Can you please post a screenshot on how this looks on your side?

Thank you in advance! 👍
