Powered by an AMD Radeon HD 6870 graphics card, Chad Smith's five-screen racing simulator looks like it provides almost the same thrills as the military's simulators, without requiring the military's budget.
I'm sure his setup is powered by an above-average gaming PC, which when combined with his graphics card is able to push a 9600x1080 image to the five LCD displays -- at a consistent rate of 84fps. Tucked behind his force feedback steering wheel is an iPhone running the iRaceDash app which connects to the iRacing game, providing real time race info like a miniature HUD.
And while we've seen setups like this before, what makes Chad's video particularly drool-worthy is the fact that he filmed it with a GoPro HD camera strapped to his head, giving us a first person view of what it's like to sit in the driver's seat. [Tecca via Joystiq]
