Anything from the Geforce 256 era and up support most of the DXTC/S3TC texture
compression formats whether it be ATI or nVidia.
The Geforce 256 only supports the most important 3 of the 5 texture
compression formats. There are 5 formats in total but only DXT1, DXT3 and
DXT5 are implemented and supported in most cases. There is little interest in
DXT2 and DXT4 which are premultiplied alpha formats.
This extension is written against the OpenGL 1.2.1 specification.
It is impossible to run most of the newer games nowdays with a card that does
not support texture compression. All the big titles like FS2004, Doom3,
Unreal Tournament 2003 rely heavily on texture compression.
S3's texture compression scheme (S3TC) was licensed to Microsoft who
incorporated it into DirectX. It is referred to as DXTC compression in
Direct3D but S3TC in OpenGL.
