Sorry for the noise. Just a comment on ATI chips ...=20 Older one have a "full" support, with 3D, but the libGL provide is the generic one from Xorg (and Mesa, if my memories are right) and doesn't provide realy good performances with those cards. Having good performances with hardware acceleration depend a lot on the libGL part (to be short, libGL provides high level functionnalities that needs to be built upon hardware facilities, the way this functionnalities are built is as important as the hardware facilities provide by the video card.) On the subject some times ago, a survey/benchmarks of video card under X (with Linux and FreeBSD) against Windows was post to some forum, it shows that ATI chips perform badly with X drivers/libGL (whereas the binary driver was almost unusable even for running glxgears under linux and unusable at all under FreeBSD.) So, yes, you may have full support, but you won't see the difference for 3D accel (I have an ATI card fully supported, when hardware accel becomes available for me, it doesn't realy change anything ... ) My 2c. --=20 Marwan Burelle, http://www.lri.fr/~burelle ( burelle@lri.fr | Marwan.Burelle@ens.fr ) http://www.cduce.org --AqsLC8rIMeq19msA Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (FreeBSD) iD8DBQFDhEv1I+2UvUKfgvgRAgmeAJ44E1GQ3JJG8mK4qvstFzUv+u0BKwCbBec0 fQ8GVXQfFSPMI3QWGX5F0BM= =v2BD -----END PGP SIGNATURE----- --AqsLC8rIMeq19msA--
