You can’t really use Wayland with Nvidia. Whether it’ll ever be possible will be up to Nvidia…if they release open source drivers, then it will. Otherwise, no chance. I have a 3080 and use Manjaro XFCE. Gaming is nearly flawless. But it’s not Wayland.
Couldn’t judge sunshine etc. as I don’t stream.
Generally, I’d say you’ll do much better with AMD on Linux, if you don’t rely on Nvidia specific features.
Thanks for the additional info. I thought Nvidia and Wayland were basically incompatible. This sounds like there’s been nearly enough progress to make this a daily runner! I’m hoping to be able to switch someday, but won’t for the time being.
