I’m getting the same issue with my new OLED deck, was wondering if it was software or hardware. Games just seem to freeze completely, and GPU runs at exactly 200mhz. It’s happened so far on Star Wars Squadrons, Battlefront 2 and Control and seems to happened after 15-20 min of gameplay. I have to force reboot the deck to fix it.

Protondb has the instructions for creating the file. It’s just a text file with a single line of code.

Squadrons, BF2015, and BF2 all run at 60 fps on steam deck. I don’t think they’ll run at 90fps on the OLED without reducing resolution too much.

Yes, check protondb. You need to add a file to the game’s folder to get it to work with steam deck, and then it works fine.

Though the HDR fix I mentioned in my other message only worked for Battlefront 2 and Squadrons, I still don’t have HDR in BF2015.

Interesting. I was thinking it was a frostbite bug, but Mass Effect was Unreal engine. So it must be something with EA’s HDR implementation.
