i've seen this in posts and i don't know exactly what it does. Mine is set to 64MB, should i change it? Is it supposed to match the memory on my video card? Also the set AGP to turbo or fast - does that just refer to setting it to 4X because i have that option but nothing in my BIOS about Turbo/Fast and when i updated my Via 4-in-1 i didn't have an option for Turbo/Fast or Default. It just said 4X which i assumed meant Turbo?

This seems a reasonable explanation

AGP Aperture Description

I got the same vid card as you.....go into BIOS setup and change it to 128....it makes a rather huge difference.  My 3D Mark scores went from 6900 to 8400 for a AMD 1.33/512 MB machine!

I haven't overclocked anything...FSB is 266 and the card is a PNY GF4 TI 4400.  I think your score is pretty decent given that you have a GF3.  

On the negative side, like alot of Athlon users, I'm getting game freezes.  My rig has been the most stable I've ever owned and the video card (just got it a couple of weeks ago) has been flawless during long sessions of Q3, Everquest, Jedi Knight, and Morrowind.

i did that twice and both times SOF2 crashed on me so i set it back to 64mb - i did notice a little extra fps though.

SoF is buggy enough that you should try the 128 apature on other games.  Run it through 3DMark and check out the results.  By the way, you can find my results at:
