Any progress on this? The config is located in AppData\SpaceEngineers\SpaceEngineers.cfg and the sensitivity value is on line 36 if you use Notepad++.The closest I can get to my source engine sensitivity (2 sens 500dpi) in space engineers is is around 0.41 but it still feels a bit wacky. I have also noticed that if I move my mouse very slowly It does not register in game. Any help is appreciated!
