If you don't have previous experience with Linux, there will be a learning curve, but depending on your hardware, it may be gentle or steeper. Likewise, your choice of distro may matter a lot, at least at first.

But you should take ProtonDB ratings as a good indicator that "might just be my hardware" is correct, at least for DRG. It also works out of the box for me on both my main rig (=currently running Pop) and the Steam Deck.
