My Dell P4 3.2 GHz with a gig of ram has a framerate of only 20 FPS with the demo version. Although the Radeon x300 PCI Express video card is on the recommended list, it is clearly insufficient with this sim on my setup. Don't rely upon the Knifeedge video recommendations unless you have an independent verification that your system is adequate. I have tried fewer colors and a lower screen resolution without much improvement. I have the latest Direct X and checked for video driver upgrades as well. If anyone has other suggestions for configuration changes (other than new hardware) I would be happy to try. Upgrading my computer with a new video card for this single application is not going to happen at this time.
