OpenGL. But with no dynamic lights. I'm no masochist.
I'm not a masochist either, I just have a beastly computer. I run it on full everything. :P
I don't have a beastly computer, but I run with everything except fog (not sure if that counts). Since I have a stupid bug with my card and the ST OpenGL Renderer, that makes most textures "solid."
Please remain civil, and do keep things constructive. That's all I ask, really. Discussions in comment threads are encouraged, but don't get out of hand. Also, remember to include a name, if you want to.
