In case it matters or you are curious, further than just windows, any games that Linux can run and have cross platform with console work as well. I’ve been playing the Finals for a few weeks now and play with other PC players as well as console players with no issues.
If you haven’t already check ProtonDB for compatibility on your steam library! Anti cheat is usually a no go but some games will work. Non steam games you’ll have to check something like Lutris/Heroic for support.
Someone correct me if I’m wrong but if you’re using stock Pop_OS it uses xorg by default as the compositor which iirc has issues with multiple monitors on different refresh rates. You can edit your .config file to enable the Wayland compositor and give it a try and see if it works!
