Except that's my point though, I even started with that... I do have a 4090 also and use it to play VR on Linux. That part IS a "normal" experience. It's the 1000mods that isn't. To clarify I mention BG3 and HLA only because it's AAA. I also play indie VR games on Linux and they "just work". One of them being built by a friend who was even positively shocked to learn that.

I brought ProtonDB up in the previous post, is that due to the SteamDeck running Linux (but on AMD, not NVIDIA) there has been a huge effort on Valve's part to make the compatibility layer "just work" so the experience a gamer had with Linux just few years ago is not the same as today.

Another source beside ProtonDB https://www.tomshardware.com/software/linux/three-gaming-focused-linux-operating-systems-beat-windows-11-in-gaming-benchmarks even though I find benchmarks to be a bit artificial at least not my opinion against another.
