AGP Window Size

[Iroquois]

Had a problem where I had to reset the CMOS on my computer. While I was putting all the BIOS settings back to where they should be, I just noticed a setting for AGP Window Size. I'm not exactly sure what this is. I set it at 128M. I figure this has something to do with either video memory or chipset bit rate.

Could someone tell me what this does. What should I have it set at. The card has 128mb ram and a 256-bit core.

The AGP aperature setting is kind of a buffer setting so the PC knows how much memory to allow the AGP bus to use.

I think AGP allows the graphics card to access system memory directly for processing textures if it needs to.

Ideally, half the PC's RAM could be used, but I reckon that would choke it. You were right in choosing 128mb as the option.

Benching I noticed no difference with it set at 128 or 256.  I have 1gig of ram but left it set at 128 as I thought it doesnt really need the 256.

Thanks Congo, I've been wondering that myself.
