The commands for the launch options doesnt work!? Im talking about the retail game and for campaign mode.
The sensitivity for crysis 2 i mega wierd! I can choose 0, 5, 10, 15.. and so on.
It's super annoying? I've tried cl_sensitivity=4 in launch options without any effect.
Any solutions or are you guys not aware of it?

Yes i got my game from elgiganten sweden today dont blame me blame them.
