Probably going to check out this for GUI stuff again soon: https://github.com/cascadium/wsl-windows-toolbar-launcher
I’m not even being rhetorical, I’m genuinely curious if there are games with significantly better performance under Linux (and I’m assuming we would have to be talking about using an AMD card so I’m also curious if that performance under Linux is better than an Nvidia card under either OS), because maybe there are and I’m just totally unaware.
But it's good to clarify a few things to avoid confusion:
1. You can use Nvidia on Linux, including for gaming. Nvidia's problems are related to lack of support for modern features (Wayland use cases and so on) caused by the fact that their blob driver in not upstreamed. But it's usable otherwise.
2. AMD drivers are open source and upstreamed, that's why it's a common preference for Linux gamers. Performance of AMD is very good on Linux (amdgpu, radeonsi, radv/aco and etc. all provide very good performance). That stereotype that "Nvidia drivers are faster" has been false for quite a while already. When comparing same classes of cards, AMD is totally on par with Nvidia if not better.
3. Besides native games, you can play many Windows only games using Wine + dxvk / vkd3d, Proton and etc. Performance in such cases usually is slightly lower than on Windows, but not significantly. The only problems now remain mostly with intrusive, rootkit styled "anti-cheats" that don't work in Wine, but I personally wouldn't even touch such games, so that doesn't bother me.
To sum up - using Linux for gaming is totally doable, as long as you want to use Linux in the first place and don't want to use Windows.
