Only running it in windowed mode/software ... looks small and awful :/
Just forget about AA and run the thing in fullscreen. I remember being slightly disappointed with the 3D models when I started playing... but it honestly becomes moot once you get engrossed in the story enough :].
I also played on a 24" monitor, BTW. Then again - I'm the kind of guy that doesn't complain about nicely done 320x200... or even ASCII "graphics" for that matter ;P.
I can't get it to run fullscreen unless I have AA on, and then I can't see all items. So, I have to run it in software mode which looks god awful and in a window, which is too small to be comfy.
