+--- Thread: [BUG] Dropping mouse input FPS (/showthread.php?tid=9670)
Dropping mouse input FPS - Null - 04-29-2023
With an increase in the load on the video card, the mouse's FPS drops to a few frames per second, while the FPS of the image and keyboard is stable. Visually, it looks like the lags of a wireless mouse, the mouse freezes for half a second. Because of this, you have to completely turn off all dynamic lighting so that the load on the video card is consistently low, but even in this case, in heavy scenes, it is very rare, but the mouse freezes (it looks like a click delay or the weapon does not shoot, many players also noticed this). Xonotic 0.8.2, linux, xorg with no compositor, nvidia, both sdl and glx versions. Maybe xorg is giving low fps mouse input to the client when the graphics card is under load, I don't know.

I think you'll find it's the CPU load, not the GPU load, affecting the mouse (and potentially keyboard) input. https://gitlab.com/xonotic/xonotic/-/issues/112#note_518719573
