I have encountered a major problem. When I am in the pause menu or main menu, my GPU usage of my GTX 1070 is at normal 100 percent. But when I try to start racing in any mode, I only have around 30 percent usage as soon as a hit the track or when I am at the garage. When I hit pause, the usage goes down again to like 20 to 30 percent. I already reinstalled various nvidia drivers and even the game itself but nothing seems to help.
