Default fps problem

could you describe how the aperture thing works
i tried all settings but nothing really seemed to change.


There is a reasonable explanation here. The AGP Aperture is
a portion of memory space, allocated to allow the GPU to
extend the total memory at its disposal. Your video card
has a local memory (64MB, 128MB, 256MB etc), and if a game
has more textures than that, they can be stored in a bunch
of smaller areas of system memory. The AGP GART gathers the
chunks of memory together, and makes them look like a block
of memory to the video card. Using DMA or DIME, the GPU can
interact with the piece of system memory. Since system memory
is so much slower than the local graphics memory, having to use
the main memory for textures is something you don't want to
have to do too much.

Some old aperture size tests:

Judging by that Tweak3D article, you never really know
whether a given game or benchmark, will have some issue
with the aperture or not. It is something you can play
with, but it doesn't come with any guarantees.
