I have an NVIDIA and I dont understand why everyone says its buggy. What kind of problems are people having? I use Nobara for AV work + gaming, it installs the propritary drivers automatically. The few games I've tried worked flawless, better then on Windows on the same machine. There's one game I've tried were I had to switch to X11 but all the others works on Wayland.
It's far better than it used to be. They didn't get the reputation for no reason. There were lots of Nvidia-specific bugs that have been slowly sorted out over the years. I'm told Wayland is even in a roughly usable state now. But it takes a lot of time to regain the lost trust. Let's see how long it takes them to support HDR, and what that support looks like.
Well up until the last driver version I was scared of putting my lappy to suspend cuz it wouldn't wake up sometimes and I'd have to directly power off sometimes causing a kernel panic. 545 was a blessing.
It depends on your card & if you're using Nouveau or the proprietary driver. NVIDIA has always been far behind in terms of Wayland compatibility when compared to AMD or Intel. Recently they seem to be putting in a lot more effort and now after Fedora officially announced that they will be dropping X11 by default in the KDE Plasma 6 Fedora Spin 18 months from now, they're likely going to be trying much harder as Fedora sets the precedent. Even if it works on your hardware rn, that doesn't mean it's yet feature complete or bug-less.
