@Ypelaarcould you change your desktop resolution to a lower resolution and set Hz higher for it (nvidia controlpanel / resolution ?
Also disconnect your Revolution Unlimited Pro Controller (hub or what ever is plugged in to use this controller)! <-- just to test , known issues with different brands of controllers.

ps some system drivers need an update also !

Which system drivers need an update? When I look for updates it says completely up to date. Thats strange. Furthermore, what resolution and Hz should I change it to?
