Since the card doesn't really have to do much, it ends up burning up CPU time, and so the end result is basically a measure of how fast your CPU can send commands to the card. That's why we use it as a quick test of direct rendering. That's also why it isn't a good benchmark; it doesn't work your GPU at all. ~ C. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkhx0/8ACgkQeCCY8PC5utDMFwCfd2EgdFpquGmSy1XpmPaPzYh1 bnAAn3Z56rX9lTQhsX0ZQVpNZRnDM50c =YLhz -----END PGP SIGNATURE----- ------------------------------------------------------- _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
