Setting up the steam deck to Run PSO2:NGS on the steam deck.
A thing of Note is to make sure you install the Proton Anti-cheat support packages (Proton Battleeye and Proton Easy AntiCheat) in the Tools section of Steam before running NGS or other games with Anti-Cheat software.
Update: I recommend Proton GE 9-10 now due to changes in AntiCheat used.
