If you think you are techy or you think you’re as smart as the average person (or smarter) just use cachyOS.
You will probably run into some issues but as long as you follow these rules you could be doing very well:
- OS drive has OS stuff and packages
- Media drive has games and stuff you care about
The two shall never meet.
Have an issue ? Wipe OS drive, in 2 minutes you’ll be back in.
Worried about configurations? Linux is all about using files for config, this pattern allows you to save files and reconfigure systems fast on the fly.
Worried about something else? Ask me.
There’s nothing wrong with using another distro.
I say use a live USB and boot into it and see how it goes. Note that it will be slower than if you were to use a drive BUT you can sort out your worries about wine performance and such right away.
Mount windows drive, use steam to locate your games. Run them to test.
Note that this is not a long term strategy, you do not want to use NTFS (windows) drive to play games. But it shouldn’t cause any issues in short term testing.
