Here's an AGP Aperture Size comparison for two cards, one with AGP 4x (Ti 4200P Turbo) and one with AGP 8x AGP (Ti 4680P Turbo) with all aperture sizes from 16 MB to 256 MB: http://www.3dvelocity.com/reviews/medusa4680/4680pt_5.htm
Interesting - with a 32Mb RAM card, the 3DMark2001 test "sweet spot" seems to be 128 - so with 128Mb on the card, it doesn't need to rely on using any ssytem memory for additional texture storage. Surprised it held up so well at 16Mb - going below 32 is usually said to disable some AGP features. Now here's a paradox for you - my motherboard supports a maximum of 768Mb RAM, but offers AGP aperture up to 2 Gb - when the usual recommendation is often half the system ram.
i have it at 128, and its the fastest out of all of them, unreal was like 20% faster when i set it to 128 and i've kept it at that ever since
nice.. but even if you get a high score you wont want a high arpeture size unless you have alot of ram. personally i prefer non-stuttering smoothness over high scores
I have mine set at 128 mg. If i set it to 64, then things get screwy in NFS:HP2 (texture misplacement)
thanks for this, I have a 4400 with 128mb and 1gig ddr333 ram I've tried 64 and 128 but have never known which to choose for best results.
mines wierd. i set it to something (128 or 256) and 3dmark keeps saying i still dont have any more than 56mb of additional texture memory (not counting the 32mb of video card ram) So i can set something and it doesnt do squat....
No matter change that option to me. I run same tests with Radeon 8500le 64Mt 512Mt sdram 3dmarks varied less than 10marks. No word about sluttering or so.
About 10-30% speed boost in the SPECPERF tests. I can personally vouch for 5-15% speed boost running UT2003
