There is a setting under Options for setting video related defaults. There is also a drop-down selection that contains generic setting that affect all video options grouped by quality.
If you pick the lowest quality, highest performance option, the game turns everything off.. and I mean EVERYTHING - players and NPCs no longer have faces, most socials are removed, dynamic lighting is turned off (making torches and other light sources useless), and the clip rate is so low that some creatures will not appear until you are almost on top of them. You will get awesome framerates and zero lag (even in windowed mode) but the game is so ugly its not worth playing. I guess it will do for bots though.
