I don’t know what to do. I’ve tried searching through google and all the answers don’t seem to work. When I use Firefox (this is librewolf but it’s the same on Firefox), games like Tetr.io or Friday Night Funkin lag real bad but they’re buttery smooth on Chrome or Chromium. I have an iGPU and a “Cedar” AMD GPU according to lspci. Someone please help me, I don’t wanna use Chromium just to get good performance. Please tell me if I need to provide more information.
I sure you have but have you tried checking the out put of
vainfo
Arch wiki since Firefox only supports Hardware acceleration with VA-API.which gen is your igpu? Older intel igpus need
libva-intel-driver
pkg installed (on Arch, not sure whats the Fedora equivalent) and the env variableLIBVA_DRIVER_NAME
set toi965
