I also have the same problem. No, changing mouse sensitivity in game doesn't help. The character basically just spin around 360 degrees even if you only nudge your mouse a bit. It is absolutely UNPLAYABLE. I've tried to find solutions for this, but none of them work for me.
- Turning off Vsync
- Playing with both the "Sensitivity" and "Hardware Mouse"
- Disabling "Precision Cursor" in the windows control panel
- Setting "bEnableMouseSmoothing" in BaseInput.ini to false.
- Unplugging my game controller/joystick
none of them works.
I've tried to update the game and also my mouse driver but no luck.
Please help.
