BeamNG stutters frequently on literally any graphics settings.

I have got BeamNG on a new PC with better hard-ware than my old one, and I've been having a very annoying issue recently that completely takes away the fun that should be experienced from this game: the game constantly stutters even when the frame-rate is very high (around maybe 60 frames). As previously stated, I have better hardware than the PC prior to this one, and my GPU and CPU usage for both stayed around 20% when BeamNG was running, yet even with a single vehicle on maps such as West Coast and Italy I get terrible frames. My old PC ran perfectly fine on the highest graphics settings, even with 10 cars, so I've been extremely frustrated about my new PC's performance. I have checked several posts on how to increase frames, and yet the game still stutters. Does anyone else have this issue? And what can I do to completely prevent the stuttering, because even on the lowest graphics settings the stuttering still occurs.

Fixed the problem: had set it to my D: drive, which is very old. Set it my C: Drive. No need to keep this thread open for much longer.
