AMD TrueAudio technology enhances audio realism by simulating the human brain’s perception of real-world sound, working in concert with the user’s existing audio hardware to recreate a lifelike experience in upcoming games like “THIEF™” by Square Enix or “Lichdom” by Xaviant Games.

Unfortunately, you can see we still fall short of that 60 FPS average; although, the 58 FPS average is indeed impressive.

At the highest resolution, we do see the card fall just short of that 60 FPS average, but considering our minimum is 48 FPS, we'd say the overall playability of the game is great.

Despite these few leaked pictures, we still do not have precise specifications for the upcoming R9 285 graphics card as it is still not clear if it will have 1792 or 2048 Stream Processors.

In The News From around the web

At the end of it all, though, if you're looking at something around the low $200 mark from AMD, this is a great option, especially this GIGABYTE version with its strong overclock and fantastic cooling setup.
The overall balance when it comes to performance is quite strong now thanks to the overclock that GIGABYTE has offered.
At the highest resolution, we see our R9 280 3GB CrossFire setup is able to offer a fantastic 56 FPS average.
Looking at the base clock of the card, the out of the box overclocks, and the bundle that PowerColor has put together, we'd say that this is a pretty strong offering.
While you might feel that these 100+ FPS averages at 2560 x 1600 are a bit pointless, the fact that we're now seeing 144Hz 2560 x 1440 screens means that we're looking for this kind of FPS now.
Combined with the 5500MHz QDR memory clock, we've really got ourselves a nice overclock on our hands today.

AMD officially announces Radeon R9 285

by Slobodan Simic |
www.fudzilla.com
According to AMD's own slide, as well as some early leaked performance numbers, the Radeon R9 285 should end up 15 percent faster than the Geforce GTX 760 graphics card and should fit well between the R9 270X and the R9 280X, at least until AMD officially launches the fully enabled Tonga XT GPU with 2048 Stream Processors which should replace the Tahiti XT based R9 280X.
AMD has now officially announced its newest AMD Radeon R9 285 graphics card based on the Tonga Pro GPU with 1792 Stream Processors.
