Ok label me a mac newbie, but I have my new 24" iMac, and I can't figure out how to update or tweak the drivers for the 7600 GT card on here. Normally on the PC side you can control anti-aliasing, AF, etc., but I cannot find these controls anywhere on here. I checked out Nvidia's site and cannot find a download for the mac. My old mac I had an ATI card which had it's own little control panel applet. Any ideas?
