okay , i was messing around in the bios and 1 of the selection in my bios is for something called apg aperture size. Before when i had a 128mb video card , it was automatically set to 128mb on the aperture size in my bios. NOw that i have a 256 mb card it went down to 32mb in the agp aperature size. Now under that selection i can select 32mb, 64mb, 128mb, 256mb, and 512mb. What does that do when you select diff aperature size? Is it like onboard video were the mobo memory is used as shared memory for you video card? does this allow me to select for my computer to use some of my system memory to use as video card memory. THanks guys.
System memory set aside for pre-cacheing for the GPU, generally setting it to the ammount of video memory your card contains gives ideal performance.
