I'm in the first tutorial and the game runs smoothly at 60 FPS 1080p in every setting, but when I just start foaming the car, FPS drop to about 10-ish and makes it unplayable, I tried all the setting from lowest to ultra and it still has this problem, my spec is not on the lowest and a bit higher than recommended, can you tell me what is exactly the problem

Spec:
GTX 1080
i5 10400F
2x8GB 3000 Mhz RAM
Windows 11
Nvidia Driver 511.79
