Last night I fired Wilbur up on my new computer, a 6 core AMD Thuban processor OC'ed to 3.6 ghz and 8 gig of RAM. I tried to crash it by creating a huge map, but it happily worked with a map measuring 4096x2048 pixels. This works out to 6 pixels = 1 mile for the scale of that map and I don't think I want or need to see if it will work with a base size any larger. Getting an artpad this evening but it's been quite fun. Program seems much more stable than the last time I had free time to play with it about this time last year.

Also, does Wilbur make use of the GPU any? (I have a ATI 5087 chipset in it with 1 gig DDR 5 vram)
