Can someone explain the difference between these 2 extensions: EXT_texture_ compression_s3tc and ARB_texture_compression.
I heard s3tc is not patent free ? is it true ?
thanks..

I'm not sure at all that now S3.com belongs to the graphic card manufacturer, http://www.s3.com/about/history.php.IP Status
Contact S3 Incorporated (http://www.s3.com) regarding any intellectual
property issues associated with implementing this extension.
WARNING: Vendors able to support S3TC texture compression in Direct3D
drivers do not necessarily have the right to use the same functionality in
OpenGL.
Is there a small howto anywhere ?
