I have a G4 450 Mhz AGP tower at work. Last year, with the announcement of Quartz Extreme in Jaguar, I upgraded the video card from the original ATI Tage 128 to an nVidia GeFORCE 2MX with 32 MB vRAM. It worked perfectly with Jaguar with no need for drivers/software. I installed Panther today, and now there are severe video/display problems: windows do not redraw properly when moved, Safari does not re-draw when scrolling, and using a standard VGA CRT it will only work at 800x600. Does anyone have any ideas? I tried looking for a driver, but the nVidia website is not very helpful, again, any suggestions?
