SOFTWARE REDEVELOPER Microsoft has shown off gaming with three 4K resolution displays using Windows 8 and three AMD Radeon HD 7970 graphics cards.
Microsoft, which picked AMD to supply chips for its upcoming Xbox One games console, seems to be interested in showing off rather impressive gaming configurations that are possible only in PC gaming. The firm hooked up three Sharp 4K resolution displays and played Dirt 3 using three AMD Radeon HD 7970 graphics cards.
Initially Microsoft tried to run the 11520x2160 resolution setup using a single Radeon HD 7970 card but according to the firm the performance, unsurprisingly given the resolution, was found wanting. Microsoft then set up a three-way Crossfire configuration of Radeon HD 7970 cards and claimed that with high settings save for shadow details and particles it managed an impressive 62 to 67FPS.
While three AMD Radeon HD 7970 cards yielded very respectable and playable framerates, apparently Microsoft forgot to choose the power supply properly. According to the firm, the measly 750W power supply unit would reset after a few minutes, strongly suggesting that the configuration was tripping an overload safety switch.
Sharp's 4K monitor is available in the US for around $5,000, making a triple 4K setup out of reach for most gamers. However, that the AMD Radeon HD 7970, a card that was released over 18 months ago, is able to attain decent framerates, albeit in three-way Crossfire configuration, bodes well for PC users, since in a couple of years 4K resolution displays will be available for sensible prices and GPU designers will produce higher performance GPUs, possibly eliminating the need to use three high-end graphics cards. µ
