havent checked what i can use yet; i've just been playing the defaults, but there is an options menu with a video settings thing. if you cant change it there, then i guess it cant be changed. it could also be machine specific. the game eats a lot of resources and they do do a pre-check on your system and set up the options based on that. so, if you're running a low end or even a medium end system, some options may not be available to you.
