The current libtxc_dxtn is only software running in cpu. With patent expired this will open up for dxtn/s3tc to be implemented in gpu drivers and running on the gpu this can in fact for programs using this compression to perform better due to reduced memory transfer between system memory and gpu memory. Why able to transfer the textures compressed to the gpu then have them decompress on the gpu. Of course this advantage most likely will not appear straight away. But this difference is a performance different to some programs running under wine being slower.
