EHHHHH.....when they say full graphics, they mean full detail, but at a VERY low resolution, not 1600x1200, full detail, 6xAA and 16xAniso. I run mine at 2xAA, full details, 1024x768 and only get around 25FPS (I have a 2.66B, 1GB PC1066 RAM, Ti4400 @ 300, 600). To be honest, I would doubt that a 1.6P4 and 64mb of video memory could even pull off full detail at 640x480. They just say that to sell the game to people who don't have the best system available. You also should turn off motion blur and light trails on your systems, anytime you use NOS or go above 150, your FPS will plummet, subsequently losing control when you need it most.
Also, don't complain about low FPS in here unless you plan to make a purchase and want help on a decision. The 9200 is a pretty bad card and you can't expect much out of it. The Ti4200 is pretty good, but gets destroyed by that game and many other new games. I would swap the 4200 and 9200, you'd get more performance for your AXP system.
Damn Rambus.
