best configuration is highly debatable because of shaders...however, here are my current settings (basically the Nice preset with some tweaks).

notice the strange resolution, thats because im on a 5:4 monitor (SXGA).
the configuration is different for games, obviously, because games have different needs. some games i play on OGL, some games with Peops soft, it all depends on waht type of game it is and what it needs.
