Spec: 32GB RAM, Core i7-6700K, GTX 1080
When disabling VSync and restarting the game, I have the typicall problem of having some weird "lines" (I don't know the correct english words, sorry xD).
When I enable VSync in the game those lines are still there. After another restart they are gone. So maybe a hint that this change only takes effect after a game restart would be nice.
