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.
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
vainfoArch wiki since Firefox only supports Hardware acceleration with VA-API.
