Last night, I changed the "Default" aperture size in my bios from 64 to 128 and ran the Mad Onion 2001 and 2003 tests. Both improved by around 1500 points plus some of the choppy video in FS2004 was reduced in high demand scenery files. I do not know if moving up to the final setting of 256 would help any more or not. My system is a P4 @ 2.8GHz with a 800MHz fsb and 1 Gb of DDR 400 MHz ram, and all running through a ATI 9800 Pro.From what I can tell right now, all I did was to allow the system to "Breath" easier and or let the data flow even faster. Anyone else have similar experience with this AGP settings?Terry

I set the AGP size to be equal with the amount of Video RAM

i set mine to 256, a good rule is set the aperture to 1/2 your system memory or 2x your video memory, and i have a 9700 pro, in 3dmark2001 i get +/-17,400 with 128, +/-18,221 with 256 btu it still hasnt cured that damn ati stutter problem.
