I have no idea why there are no news about this on English tech sites, but anyway...
Here's the link to the site, but you won't understand much since it's on Croatian.
It basically says AMD is partnering with Crytek who will implement Mantle into CryEngine to offer up to 45% better performance than DirectX.
There are also three new devs who joined AMD's Gaming Evolved program, Rebellion Developments, Square Enix and Xaviant, and among the games which will use Mantle are Sniper Elite III (Rebellion) and Murdered: Soul Suspect (Square), while the adventure Lichdom (Xaviant) will offer support for TressFX hair and AMD TrueAudio tech.
What do you think?
