Hi Brolin, Sorry to hear that.
The ground is using a shader that makes the texture of the rocks, cliffs and the rest have a 3D pumps and stuff like that, but in-order to render all these details it requires Direct X 11 or above to be installed.
Can you please let me know if your computer specs are above the minimum tested specs that I mentioned in the front page?
Thank you.
"System Requirements (Minimum tested specs)
