Just a heads-up for those who have ATI cards. They've released new catalyst 3.1 drivers for DX9. I've installed them and they improve ops quite a bit. At least on my set-up. I used to get a lot of "flickering" when loading games with the 3.0 driver and that doesn't happen anymore. Blending of the textures colors is improved, and AA works a lot better!
Also the new drivers apparently have M$'s blessings
No pop-up warnings about the drivers not being certified for XP.
