If the hardware can't do S3TC, then the driver can simply not advertise the availability of the extension, and if the application expects the driver to compress the textures, then the driver can either refuse or just pass the textures on uncompressed. Clearly the driver can't implement the full API, but is there a legal barrier to implementing the part that says "here, take these pre- compressed textures and give them to the hardware" ? > Can we add this to the FAQ, please?
