Specifications

The Intel i845 and i850 specifications contain the following statement:
AGP 1.5 V Connector support only. No support for 3.3 V or Universal AGP connectors.
However, this should not be an issue for GeForce cards, as apparently they are AGP 1.5V devices.

Q. Does the GeForce support Texture Compression (DXTC/S3TC)?
Q. Can I use the compressed textures on the second Unreal Tournament CD with my
GeForce?

This information was sent to me by NVIDIA's manager of developer 3D tools and technology:
S3's texture compression scheme (S3TC) was licensed to Microsoft who incorporated it into DirectX. It is
referred to as DXTC compression in Direct3D. The GeForce supports all five texture compression
formats in Direct3D. With the 5.xx (Detonator 2) drivers the GeForce also supports S3TC texture
compression in OpenGL.

You can use the compressed textures in Unreal Tournament if you download the latest OpenGL renderer.
See the 'How can I speed up Unreal Tournament on my GeForce?' question for more information.

Q. What should my AGP Aperture size be set to?
Q. How can I change my AGP Aperture size?
It should be set to half your system RAM if possible, and if not it should be set at some point below or equal to
the amount of RAM that you have. However, it is possible to experience speed advantages of 2-3 fps from
setting the AGP Aperture size to 256 regardless of the amount of RAM that you have, and there are some
games that may have visual problems fixed by setting the AGP Aperture size to 256.
Beware that setting the AGP Aperture size too low (below 32) will actually disable AGP which will cause a
speed decrease, although stability problems may be solved - see the 'My GeForce keeps on locking up or drops
me back to the desktop during 3D applications. How can I fix it?' question for more information.
There are also some programs that have problems (stuttering, flashing or corrupted textures, blank screens)
when the aperture size is set too high. Experiment and see which setting is best for your system and programs.
It's possible that if you set your AGP Aperture size to 256 you will be able to load the 64MB texture test in
3DMark2000 even if you haven't got enough video memory. In addition, if you set the aperture too large you
may get 'Out of Memory' errors - see the 'I get 'Out Of Memory' errors although I have plenty of RAM
installed. How can I fix it?' question for more information.
You can only change this in your BIOS setup - it may be called something slightly different, so look for a
setting that is measured in MB and can be set to values such as 16, 32, 64, 128 and 256. Different motherboards
allow different settings - for example, i815 motherboards will not allow you to set the aperture size above
64MB.

Q. What are the recommended BIOS settings for a GeForce?
Note that the settings in
italics may have to be changed in order to maintain stability on some systems. The
changes that may have to be made to them are detailed in the instability section, and in particular the 'My
GeForce keeps on locking up or drops me back to the desktop during 3D applications. How can I fix it?'
question.
