AGP apeture size?

[Inside_line]

nice one acnebrain, definitely good to see the 256 onboard is really working well. It would be interesting to see someone post results of a 6800nu w/128. I dont think 400 points in 3Dmark01 is that huge... oc the onboard memory some more and I bet you could turn that 400 into 500 with the smaller aperature setting.

Conclusion (yes I'm writing it first):

A) 256MB on a 6800GT is too much, or
B) 3DMark03 is not a sufficient test

Score went down as apeture went up. CPU limited anyway.

This is the only one that showed any kind of increase. It was simply an additional 2.1 FPS in game test 4.

D3/HL2 are probably going to make the extra memory useful. I am not going to be doing any game test though.

all those scores are within the margin of error---that and I would seriously doubt that 3dmark03 is going to overflow the 256MB on ur 6800GT.

Test it with Far Cry at 1600x1200 4xFSAA, 64 or 128-tap Ansio and max settings. (or Halo with the same settings if u dont have far cry)

Isn't AGP aperture only[/i] being used when the graphics crad itself runs out of onboard memory?
And thus can "lend" system RAM, to accomdate textures ect., but only upto the size that the AGP aperture size is set to in BIOS?
And that the old "rumour" abot same/double AGP aperture size comes from the time when cards had 16-32 MB onborad RAM?
For what games use more than 128-256 MB texture memory?
And could someone find a test, to supports these claims, as I have the feeling that the AGP aperture size today has the "same"(less than) impact as the difference btween 4xAGP and 8xAGP?

I think you are right, but there are reviews and guides out there that say that you get different results from each different setting. For instance say you have a 128mb card, setting the AAS to 64 might produce a negative proformace affect on the card whereas 128 makes it run good or normal. I'm not saying 128 is really the best setting for a 128mb card. I think this is one of those things you just need to try each setting for.... When you get bored load up 3dmark and test each setting out.
