Turn off the setting to disable of the touchpad when typing. Basically whenever you press a key, it thinks you're typing, touchpad gets disabled and you can't look around.

It's great when palm rejection doesn't work well but problematic when you do want to use the keyboard and the mouse at the same time. Modifier keys are ignored so you can do things like Alt+Drag your windows but pressing W will trigger it. Hence, can only look around when sprinting and the W key has been released.

I suspect that there is “palm check” turned on for your touchpad. This is designed to keep you from accidentally moving/clicking the touchpad by brushing it with your palm while you are typing.

Look for a “palm check”, “palm rejection”, or “disable touchpad when typing” setting in your touchpad utility. As far as I know, these are all roughly the same thing.

Have you tried a mouse instead?

This sounds like a setup for a challenge run lmao

Disable resolution scaling for your desktop perhaps, or make sure the game runs in the exact same resolution.
