FYI, I checked in this code so the depth buffer at 24-bit depth is now only allocated as 16-bit and the difference is used for textures. Of course renderering is still pretty slow at 24-bit depth compared to 16-bit. -- Leif Delgass http://www.retinalburn.net _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
