I have a steamdeck and just could not get used to gyro, i hatdd jt so much. But the steamdeck is heavy and i usually have it resting on a pillow or something so i dont have to support the full weight. Also the screen moving whenever you move gyro bothered me a lot, i dont want to have to be moving my neck and arms around to play a game. I could see it being a lot better with just a controller and a screen in fixed position though, but i like to play games in handheld mode and i think itd be frustrating switching back and forth.
Yeah idk, i tried it wirh spec ops and hated it, but the aiming in that game felt weird no matter what, i disliked it with the touchpads too, and ended up just using the joystick which i barely ever do for anything that involves aiming. Ive heard Doom 2016 is a good one to try it out on so maybe ill try that, i just do like to have the steamdeck resting and pretty firmly planted on something when im playing to rest my arms.
