I installed 10.4.6 on my computer today and finally got the 6600GT to run at 1680x1050 (LCD though). The problem is it's sooooooo slow. I've installed Lightroom and Aperture but they are unusable at this speed. I ran Xbench and surprisingly I got 6.71 !!! mofo pos. Here are my brief specs:
AMD Sempron 3100+ 3GHz
1GB DDR RAM
Nvidia 6600GT 128MB AGP
I don't know what the problem is. Can somebody please help improve the performance. Thanks in advance.
