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.
which gen is your igpu? Older intel igpus need
libva-intel-driverpkg installed (on Arch, not sure whats the Fedora equivalent) and the env variableLIBVA_DRIVER_NAMEset toi965.See also https://wiki.archlinux.org/title/Hardware_video_acceleration#VA-API_drivers.
According to fastfetch it’s a “Intel Xeon E3-1200 v2/3rd gen core processor”
When I tried to run “LIBVA_DRIVER_NAME=i965 firefox” it spat out “restorecon: SELinux: Could not get canonical path for /home/[myusername]/.mozilla/firefox//gmp-widevinecdm/ restorecon: No such file or directory.”
