Just made the switch at the end of December alongside making my new PC. Feels very refreshing to actually be in control of my own computer. I’ve barely run into any issues gaming either, which is a welcome surprise - Proton remains one of the best things Valve has ever done.

Yep, main returns an int in C++. It’s for the return code - if it returns 0, that indicates the program ran ok, if it returns anything else some sort of error occurred.
