I don't believe that 945 graphics have hardware anti-aliasing. However, some mailing list posts turned up on google suggest that you should be able to have software AA for a corresponding performance hit. What do the MS Num and MS Bufs colums in glxinfo show? One thing some googling is showing me is that AA is apparently no longer as simple to setup as it was on SGI systems. _______________________________________________ geda-dev mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-dev
