I got about 3-9 fps with it on an AMD Athalon X2 64 Dual core processor with an nVidia GeForce 6150 LE graphics card. However, shortly thereafter I discovered that my brother had left his "Lego Rock Raiders" disk in the drive and that he had somehow managed to keep the computer in Windows 95 compatibility mode.

Nice! Very nice! One suggestion about the first pic of the train over the foggy gorge: make the sides with slopes and jagged like a canyon and not drop 90 degrees like it does there. It will look alot better, but the rest is spectacular! -Chris
