Hi ,
I bought an used 512gb steam deck and so far I have tried shadow of the tomb raider the demo , mafia 2 definitive edition and tomb raider 2013 and all the games keep crashing , am I doing something wrong or was I sold a faulty unit ? Can anyone advice ? Thanks
View the Steam Properties for a game, and in the tab that says Compatibility, check the box that says Force Compatibility and select Proton Experimental.
Did you reset it to Factory settings before setting it up for yourself?
