Seems to be every click, the stuttering effect is so bad that it occurs everywhere in the main menu. You just hover over a menu item, takes forever to respond and the animation isn’t even smooth. It’s frustrating, when trying to even select a departure airport, takes multiple clicks if it responds to select Set as Departure. Then once in the cockpit when I try to pan around using the mouse same stuttering, used to get 40+ fps on high settings now can’t get past 7 fps. I’m reinstalling the sim a 2nd time.
