CPU 100% GPU 30%

since the new update 0.26 came out, my game started to do some crazy stuff. I already fixed it with a fresh install or whatever you call it, but now my game runs at 100% cpu ussage and 30% gpu ussage (before the update came out everything was fine). It doesnt matter how much i lower my settings, it stays at 20 fps no matter what. Drivers Reinstalled and checked if the system somehow wants the CPU to render but it didnt change. AI cars are at 4 but even if i set it to 0 nothing happens. It doesnt thermal throttle or anything.
