My terrain is grass everywhere, even inside caves, etc. I've browsed other threads and I've tried reinstalling the game & patch, which seems to be the most suggested solution. My drivers are set to update automatically (unless graphics card drivers aren't included in automatic driver updates?) and just ran an update last night.
I tried changing the rendering subsystem, but the game wont save the setting to OpenGL. I've tried changing it in-game, in the login screen, and even manually in the game's documents. Still is set to the "direct" render.
If it matters, I have a Dell computer with Windows Vista.
I'm not really tech savvy, so bare with me when it comes to explaining how to do complicated processes.
