sliding

Hey everyone, I am missing something really simple but can not figure out what it is. I have had this before, but years ago so I have forgotten the fix. Brand new track mesh. Realroad textures are correct. The grass/terrain is normal and has grip. The road, as soon as you get on it the car...

I'm having frame rate issues when my car is sliding or spinning which makes recovery almost impossible. Can someone please give me some ideas to solve this issue? I'd be very grateful. specs: windows 10, intel i5 9600k@3.7GHz, 1080ti, 16Gb ram
