q3 + r300 = good (Score 1)

This upcoming release of the Quake 3 source code coincides nicely with the latest r300 project update (http://r300.sf.net/): the open-source ATI R300 drivers (for Radeon 9500, 9600, 9700 and 9800 cards) have been moved into the Mesa CVS at http://freedesktop.org/.

See http://dri.freedesktop.org/wiki/ATIRadeon for more info about Radeon cards and chipsets.
