Just got started with this game (PC - Steam version). It's fun so far. I had really wanted to use my controller. But, the aiming movement is so sluggish. I've tried pushing the "Aim Sensitivity" up to 10, but still felt like I was turning through molasses. Is there anything which can be done to speed that up, or is the controller just fundamentally slow on PC?

Using an Xbox controller via Bluetooth. And the issue isn't lag, it's the rotation speed in game.
