Linux is way easier than it was even 10 years ago and many games run better on Linux than they do on Windows. There’s gaming distros but I’m not sure what the benefit is other than the built-in NVIDIA drivers. I just game on Fedora. You need to enable Proton stuff in the settings and you’re off.
Just something to bear in mind regarding OneDrive; the unofficial clients don’t have access to certain APIs that the official clients use meaning that it only syncs every 5 minutes at best. As far as I know there’s nothing you can do about it.
