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.

Firefox Hardware video acceleration

If hardware video acceleration is blocked with error code FEATURE_HARDWARE_VIDEO_DECODING_DISABLE or FEATURE_FAILURE_VIDEO_DECODING_TEST_FAILED in about:support, you can override it with media.hardware-video-decoding.force-enabled=true. See [10] for more information. Alternatively, you can install firefox-vaapiAUR.

Also make sure that in about:support Compositing in the Features table under Graphics is set to WebRender if it is not than set gfx.webrender.all in about:config to true.

I had the same issue but I have a NVIDIA gpu. but I just had to install libva-nvidia-driver and edit Kernel parameters and Environment Variables . I got this to work with both Firefox and Librewolf but only some video codecs.

note i have 1080ti so i don't have hardware acceleration for av1. also the only time a problem when I turn off hardware decdoing on firefox is when I watch a HEVC stream on twitch for some reason i get drop frames every second.

Did all that but it's still the same. I really don't know what's the root cause of this.

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.

This is what I got, I still dunno what it means.

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 variable LIBVA_DRIVER_NAME set to i965.

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."
