After starting JC2 the menu seems fine without lagging. After I start playing the game and go from game to the menu or mapmenu (F1) there are 2 short lags where the screen kinda freezes for like half a second and goes normal after those 2 lags. Thats really annoying and I want this to be fixed. Playing the game doesn't make any lags.

I easily pass the system requirements of the game and I also tried to change the graphics settings to low, but this wont fix it.
