CloudSkipper -- Let us know how your system performs with FS One. We've tested FS One on a laptop with a 1.6 GHz Mobile Pentium CPU, 512MB RAM, and an ATI 9200, and it performed fine. More memory would be nice (1 GB is plenty) and a better graphics card will help you get better frame rates, but your system should be fine. Be sure you have the latest drivers for graphics and sound and be sure to use the latest patch of FS One.
