When I try to play with a controller I keep getting the input change notification which resets the camera. It just constantly and rapidly goes back and forth between keyboard and controller. The game is unplayable like this. Help. I cannot play this game with a mouse and keyboard.

Should go back to controller once you push any button of gamepad. Which one do you use? If it's some random controller with X360ce there might be a problem. I'm not sure if X360ce knows what's A Hat in Time. Thus it cannot work with it

I'm having the same problem. Using a PS4 controller with DS4Windows. The inputs work, but the controller/keyboard notification on the left side of the screeen keeps switching and it's too annoying to put up with.

Try running the game without DS4Windows, the game should register the controller as a DS4 on its own.

Yep, I tried that after posting and it works fine that way. Thanks.
