Screen resolution 1024 x 768 & 32 bit color, everything else is default for my video.
For in game settings (GTASA) the only things I've reset are the controller options, the rest is as it installed.
Have not messed w/ framerates, overclocking or any of that.
By "flies", I mens the video is smooth, loads are quick. The only video glitch I see is the slow render (the occasional tree
you don't see till you hit it), but it's still better than the PS2 version.
Hope this clears things up, if not you know where to find me.
