Hi all,

I recently installed Debian 12 on my Lenovo Legion 5 Pro, and am using the GNOME desktop (x11). From time to time I play a game called survev.io . It’s a browser battle royale game, not hard on graphics.

I have an Nvidia rtx3060 and have the proper drivers installed. I checked using nvidia-smi and Firefox is using the Nvidia gpu.

The issue is that the game runs smoothly until I press a button or move the mouse. Then the framerate decreases significantly and it becomes unplayable.

I already tweaked the following settings in Firefox to no avail:

  • gfx.webrender.all = True
  • enabled hardware acceleration
  • layers.acceleration.force-enabled = TRUE
  • gfx.x11-egl.force-enabled = true

And now I’m out of ideas. The game itself isn’t too important to me, but other browser games do the same, so it’s a wider issue I want to solve.

Any ideas on how to resolve this?

      Incorrect, actually. Firefox for Android uses Gecko like the desktop version, while the iOS version is stuck with WebKit.

      It’s not tho. Their FAQ page explicitly says they’re not chromium based (and they speak of both desktop and mobile) Wikipedia also says firefox mobile uses the Gecko engine, Chromium isn’t mentioned.
