With this feature, Matrox offers well-to-do gamers an entirely new gaming experience where one perspective is rendered across three monitors.
Here, one's perception is extended through a sort of panorama effect. Surround gaming is already available with many games today, for example, all games based on the Q3 engine (RTCW, Jedi Knight, Voyager, Soldier of Fortune II, etc.). Even Microsoft's Flight Simulator can be played in this mode. Basically, any game that has variable FOV (Field of View) settings should be adaptable to surround gaming.
In any case, Matrox is convinced that surround gaming will give well-off customers the ultimate gaming experience. According to Matrox, many users already work with two monitors, so purchasing a third monitor wouldn't make that big a difference. After all, in the days of 3dfx Voodoo2, lots of gaming freaks went out and bought a second card for SLI operation.
There's no question that surround gaming is a special experience, but there's not going to be a whole lot of users who can really afford it, or want to spend the money on it.
