I loaded AFPD on my wife's Dell Dimension 2350. Has 1 1.7 Ghz Celeron processor with three PCI slots and on-board graphics - no AGP slot. FPS was 6 to 10, slow simulation. After checking the price of a new computer, I decided to try an ATI Radeon 9200 graphics card with PCI connector for $89+. FPS went up to 27 to 116, dependent upon options and scenery. Beats buying a new computer. Beats G2.
