I know it’s not the best
Didn’t pay thousands for top of the line ryzen and nvidia gear for “not the best” gaming situation.
Linux falls short on two major fronts, less idiot proof, less gamer friendly, and that’s Windows’ largest market shares, idiots and gamers.
If you use this guide to mount the Windows drives you can run it and Linux side by side. It works just as good as Windows these days for 90% of games. You can add games downloaded from unofficial sites to Steam as a “Non-steam game” and it works. Installing Nvidia drivers on Mint is easier than Windows, there’s a built in utility.
There’s another launcher that I’m forgetting the name of that will launch Epic and GoG games. Following that proton guide should make NTFS (windows) drives usable for anything in Linux though. I can boot games downloaded from “alternate sites” if I add them to steam as “non steam games” regardless of how the drive is mounted.
