Basically, I have a laptop (5800H/RTX3050) and Windows is irritating me to no end. I am thinking of completely formatting it and replacing it with whatever distro can give me the best gaming compatibility. For reference, I play - CS:GO, DoTA, Asphalt, and a little bit of Overwatch.
I was thinking of Arch since SteamOS is based on it but would like your opinion on it.
I was in that same boat about a year ago and I switched to pop_os as a trial for a while before fully committing to it. Works well with Nvidia and steam and I know for sure Dota works on it. I have found that any game that is steam deck verified (or even playable) works on pop_os without issue.
