Sound and graphics bug

i have a 2080 super 32gb ram and a 5600g. im running the game on medium to high settings in 1440p without ray tracing or path tracing. all the latest drivers. but when im driving the car is glitching. not affecting my driving but the visuals. you could say its vibrating. and my audio is just randomly cutting out, changing volume and tone when im in game and when im driving. this doesnt happen in any other games. any help would be much apreciated
