Linux user here running FF, no real dealbreaker issues at my end.

Now all they need is a complete nvidia-settings application under Wayland that allows for coolbits to be set, and I may be able to use Wayland. For some reason, my RTX 2070S boosts far higher than the already overclocked from factory boost clocks, resulting in random crashing - I have to use GWE to limit boost clocks to OEM specs to prevent crashing.

Strangely enough, this was never a problem under Windows.
