Some points to fix (or maybe there is already a solution?)
I have stuttering when I look around with the mouse (feels like 15 FPS), when I use a controller I can look around smooth with the right stick (no stuttering!)
It stays the same when I lower the details and resolution, so it doesn´t seem to be a performance problem
I can´t change the resolution in fullscreen mode, only in windowed mode! In fullscreen mode it´s only "Custom" available, and I see 3620x2036 as available resolution (but I can´t choose it)
The controller doesn´t work in the inventory
I can´t choose mouse and keyboard in the control options, only "automatic" is available
