Set the accelerated graphics port aperture size to 64 megabytes or to 128 megabytes

If you are using an accelerated graphics port (AGP) video adapter with less than 32 megabytes (MB) of memory, and the AGP aperture size is set too low, some games may crash and some games may not run. We recommend that you set your AGP aperture size to 64 MB if you have 192 MB or less of total system memory.

If you have 256 MB of system memory, or if you have more than 256 MB of system memory, set the aperture to 128. Higher settings do not have a significant effect on performance and actually increase the size of the Graphic Address Remapping Table (GART), although the increase of the size of the GART may sometimes have an adverse effect. The AGP aperture size is a setting in the BIOS of many computers. For information about how to adjust the AGP aperture size, contact the manufacturer of your computer or of your motherboard.
