Didnt solve the stuttering, but .. wow dude .. you helped my game to work way more proper!
Before these graphic-options, parts of the environment (like on the fleet, the holograms and cantina-visitors) always turned invisible. Now they are always there, no matter on which distance I move. Hopefully it stays like that!
Alright, it helped for the first but.. turned out that it didnt help that much as I've expected.
