A lot is certainly due to the driver. The DRI CVS trunk has a new radeon driver which utilizes the chips' TCL unit and can optionally use page flipping, with that I get 1500 fps in 32 bit and more than 1800 fps in 16 bit with a 7500 Mobility in a PowerBook. Not that glxgears is a very important or meaningful benchmark... -- Earthling Michel D�nzer (MrCooper)/ Debian GNU/Linux (powerpc) developer XFree86 and DRI project member / CS student, Free Software enthusiast _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
