My dummy frugal self bought a used 64gb steam deck with a 1tb upgrade. It keeps crashing!!! At first it was just cyber punk now it’s ANYTHING I play even my friend Pedro and postal 2 which aren’t very demanding games. This can’t be the intended result??? I’m honestly just sad I probably got burned thinking I got a good deal. Additionally my vram is only showing 4gb total although I changed my VRAM to 4gb. My 3DS was running better and I’ve had that for YEARS. I don’t understand how a 3 month old deck can’t keep up with:/
Others can chime in but you may want to reset and fully reinstall SteamOS. The other thing is - do you which brand and model 1TB NVME is installed? If it’s a really poor quality one, it could cause issues
