Since the driver updated to 430.26, flipping gets disabled randomly and stays disabled. The only way to fix it is to reboot the system. I can’t play games, mostly American Truck Simulator, without flipping because the game runs like a comic book when flipping is disabled. The frames are displayed as 60 per second but despite that I can see the game running with a lot less frames when flipping is disabled.
