Although probably one of the best driving simulators available for the PC, iRacing's graphics leave something to be desired. The latest chapters in the Forza Motorsport and Gran Turismo franchises look much better despite running on the ancient graphics hardware in the Xbox 360 and PlayStation 3, respectively. There is one thing iRacing on the PC can do that its console counterparts can't, though; check out this awesome five-screen setup shown off by YouTube user chadsmith20:
I know, you can wire up three Xbox 360s to power a triple-screen setup in Forza. But this rig has five screens, even if the helmet cam used to shoot the video doesn't have a wide enough field of view to capture all of them at the same time. Another look at the setup, which is running at 9600x1080 resolution on a Radeon HD 6870 Eyefinity Edition, can be found in this video.
I've been doing some game testing at 5760x1200 spread across three monitors, and while it takes some getting used to, the extra screens can really add to one's immersion in certain games. Batman: Arkham City isn't one of them, but first-person shooters and driving games are particularly well suited to the wider perspective that additional displays can provide. With halfway-decent 1080p panels getting cheaper by the week and both AMD and Nvidia pushing their own surround gaming technologies, multi-screen setups may become increasingly popular among PC gamers. We certainly have the horsepower to paint pixels across additional displays. Thanks to Joystiq for the tip.
