       # Driconf: enabling S3 texture compression on Linux

       **Update: the DXTC patent expired on 2018-03-16, many distros enable this by
       default now.**
       
       S3TC (also known as DXTn or DXTC) is a patented lossy texture compression
 (HTM) algorithm.  See: »https://en.wikipedia.org/wiki/S3TC« for more detailed
       information.  Many games use S3TC and if you use Wine to play games you
       definitely want to enable it if your graphics card supports it.
       
       Because this algorithm was [patented it is disabled by default on many Linux
       distributions]( https://dri.freedesktop.org/wiki/S3TC/).
       
       To enable it you can install the library "libtxc" if your favorite OS has not
       installed it already.
       
       For easy configuration you can install the optional utility DRIconf, which you
 (HTM) can find at: »https://dri.freedesktop.org/wiki/DriConf«.  DriConf can safely be
       removed after configuration.
       
       
       ## Steps to enable it
       
       
       Install libtxc_dxtn:
       
       ArchLinux:
               # pacman -S libtxc_dxtn
       Debian:
               # aptitude install libtxc-dxtn-s2tc0
       
       
       Install driconf (optional):
       
       ArchLinux:
       
               # pacman -S driconf
       
       Debian:
       
               # aptitude install driconf
       
       Run driconf and enable S3TC:
