I have been running Debian sid for 23 years and I play all the games I want with minimal issues I couldn't work around. it may not be for everyone but works great for me. the debian wiki is great and using timeshift there is nothing so far I couldn't recover on.
I have used Nvidia in the past (RIP Evga) and now use AMD both worked great but AMD is easier since I don't have to do anything. also great tip the arch wiki is great for help as well.
Just need to rember it's not cut and paste there which you shouldn't do anyway but points you to the fix and just need to find the file or program equivalent for debian.
