There are two problems for Mesa. 1. Compressing raw textures to the S3TC formats. As was mentioned later in the thread, there is an extension that exposes DXT1 without this requirement. 2. Decompressing textures for software fallbacks. As far as I'm aware, all of the drivers still have some software fallbacks, so this support is still required. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkiFA9MACgkQX1gOwKyEAw/k/ACghQypfRsexjF8wqa5UxoyYQ9p 1QEAoJILJ536IDND19uARMZO91w8dtZ4 =1wRL -----END PGP SIGNATURE----- ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
