Invisible track!

Normally there is a small track that runs along the ground where the pictures show. Well, there kind of still is. its just not able to be seen. I was driving along and I just got launched into the air. I'm like "what the heck?!" Its entertaining glitch that's all. Also, there is a weird wall in the middle that you can drive through that likes to run away fro you. You can see it in the 3rd picture.

 

Have you got any Gridmap mods installed? Try removing them.
You could also try deleting the cache.

 

Turn up your mesh quality, only way to fix it.

 

Just as others have said..

Lowest Mesh Quality locks LODs too low to render some things...

It's a mild bug just use LOW... NORMAL shouldn't be needed but if problems presist than turn it up to Normal.



In my experience low is fine just avoid "Very Low/Lowest" like the plague.
This is also very good for med end GPUs to get that extra bang in FPS you need.
