Vista - AGP Aperture Size

What is that?
How do i change AGP Aperture Size?
How i get to the Advanced Bios? (It is not ctrl f1 on my Notebook)

AGP aperture size will not increase performance graphics wise, its the amount of allocation from your system ram to work in conjunction with your graphics memory, it means that some of your system ram will be used to "bail it out" if need be, in other words, if you got a sweet gpu, theres no real reason to have this on. if your using onboard graphics, theres more use for it as most onboard graphics cards use AAS for their primary function. this however is optimized and shouldnt be fiddled with.

Well, as you know GTA uses a lot of Space

To run it smoothly, i would need kinda 1 GB of VGA.
So, if i set AGP to 768 MB i would have 1 GB.

no it doesnt affect your actual gfx ram, mine is automatically set at 2gb and it shows up on my directx diagnostics, but it still shows as 896MB

But then again, how do i set the AGP?
It needs to be in BIOS?
How do i get Advanced Bios in American Megatrends Bios?

press either f2 or delete to access the bios, but I warn you, this shouldn't be messed with, or you will be logging on to here with somebody elses computer trying to fix the newly created problem.

AGP aperture size is only relevant to machines that have AGP ports. It was a way to allow the video card to map more memory when cards only had 16 or 32mb of memory on them. Of course the mapped system memory was slower than dedicated memory, as it was travelling through the AGP bus, but it was faster than flushing the cards memory and loading all new textures.

Your ASUS G2 doesn't even have any options in the BIOS for AAS, as it doesn't have an AGP port. Extra memory should automatically be mapped through the PCIe bus.

So don't worry about it.
