>From what I understand, 24bpp is the same amount of data as 32bpp. It just signifies that there is a separate alpha channel. Since this is not strictly 'color' the last 8 alpha bits are not counted in the color depth. Still, each pixel takes up 32 bits of memory. ATI cards do 16bpp just the same as all the other cards, 16 bits of color and nothing else. (red and blue get 5bpp, green I think is the one that gets 6bpp) Josh _______________________________________________ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
