Strange, I played on 4500dpi (considered low by a lot of people who play games) and the turning is way less sensitive than what you are describing here, I will definitely look into that
I'm on 1000, and even my mouse pointer speed in windows setting is only about 50%. Hmm, I wonder if it has to do with resolution or something. I've never really made a first person game like this so I'm not too certain on how the math works out.
Yeah that's weird, I'm on 4K resolution but not sure if that will help, if possible you could try decrease your sensitivity even more and see if that helps at all, would love if you could try the game properly, if not it's fine though
