Apparently people use it in Fortnite with the PS5 controller.
If you think about it, a good controller could be just as accurate as a mouse if not better. It seems more intuitive than using a mouse.
I’m gonna try it out when I get the new steam controller. I’ll use the sticks for looking around and the grip detection to activate gyro so I can use that to aim precisely. I’m already pretty competitive with both controller and KBM, so I’ll see how it goes.
