AGP 4x

Hi chaps, I have a soltek 75kav mobo, with a Hercules GF2 32M, running win98 not SE. I have a SE cd, though. My mobo has no issues with AGP4X, nor does the GF2, but switching it on and off doesn't make much difference. I believe there is some issue with w98 and this. Is there anything I can do to get it working? Will I get much extra performance if I can (ie is it worth the trouble)? Would upping to 98SE make any difference, and can I do it as an upgrade, or would I have to do a clean install? Thanks guys. R. PS. Still getting better performance with AGP aperture at 16m, after extensive testing, and applying all tweaks suggested by Hercules. Got better performance by doing the virtual memory bit, and defragging the disk. So am running quite well, now. No glitches in GPL at all. -- Posted from motgate2.mot.com [136.182.1.10] via Mailgate.ORG Server - http://www.Mailgate.ORG

AGP x4 will give you virtually zero performance increase in most games. See http://www.tomshardware.com/mainboard/00q1/000214/index.html for more details, and sepcifically http://www.tomshardware.com/mainboard/00q1/000214/agp-08.html for Quake III benchmarks at 1x, 2x and 4x AGP Ian

AGP 4X only helps if you are both a) running a game that uses more textures than your videocard can cache locally and b) have sufficient main memory bandwidth to actually make use of AGP 4X's higher POTENTIAL transfer rate (you need PC133 system RAM in order to feed the AGP bus at a 4X rate). In your case a) is probably not true, especially if you are using GPL as the benchmark. That would also explain why you only need a 16 meg AGP aperture. If you were running a texture heavy game and b) was not true, all that would happen is that the bottleneck would move from the AGP bus to the system RAM and you would still get no appreciable benefit.

Yup, you would never WANT agp 4x to make a difference, because your system would be so sloooowwww. Only if you have a very modern game (like N4) with full detail, 32bit colour, running on a 32mb or less video card would you see any difference. You will never want your video card to be using agp 4x, because it is a LOT slower than the video card memory. FPS would be terrible. Rafe Mc

I think AGP 4X can be of benefit in some situations, for instance, when using hardware vertex processing, if you have your vertices buffered in system memory and need to copy them to VRAM every frame (they need to be in VRAM for the card to use them with h/w VP), AGP 4X would speed this process up. That's a fairly limited example though, since you only have vertices in system memory if you need to alter them frame by frame. For instance, this is how you would do a layer of 3D animated water.
