Following up the early first-hand impressions of the game, a handful of new technical details have emerged. Most interesting of which, is that the video menu now seems to have an option to enable MIP Mapping. For those unfamiliar with the term, basically, MIP Mapping is a technique used to smooth out textures as they get further away from the camera. This will help reduce some of the flicker or "shimmering" of detailed/high contrast tetxures (such as bricks) which was rather noticeable in both GTAIII and Vice City for the PC.
Another new option said to be in San Andreas is the abilty to adjust anti-aliasing settings from the game. While not a major technical breakthrough by any means, it will make tweaking video settings quite a bit easier than having to exit the game to adjust them from desktop display options every time.
