@LukeAlmighty That doesn't look like a big issue.
It's not the texture that's the problem, since it's an entire object, it's likely a bad LOD setup or setting.
That is how the rock is supposed to be rendered... when it's really far away.
So it's just a simple setting to correct, or maybe the wrong asset was placed, either way it's a minute or two of work at the most.
Definitely the sort of thing you can fix in a Beta before release.
The settings or graphics card don't matter in this case.
