I have a P4 2.53 Ghz Northwood /w 533 FSB 512 Megs of 1066Mhz RDRAM GeForce 4 Ti 4600 /w 128 Megs of DDR 160 Gigs of HD space I checked the region folder after I compiled the map, it was ony 80 or so megs. And for me it took only about 20 minutes to build the terrain. I wont be making another one of these maps. It took several hours to make the greyscale image.
