I just plain don't understand why PseudoColor emulation has to be so expensive. Can't you just do it in the same manner as the ShadowFB layer, whereby the screen representation is updated only every 10 ms or whatever? Certainly it will be more expensive than a RAMDAC register write, but it seems like it should be quite reasonable on a modern machine. (I can imagine a bunch of optimizations that are possible to handle the colormap-animating client, but I don't even think they should be necessary at all.) -andy _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
