A more relaxed Johan talks us through Mantle. A must watch for enthusiasts. 

Johan Andersson from EA/DICE, makers of Battlefield 4™, talks about AMD's Mantle API, why he's so excited about it, and what he believes it means for the future of PC games. Included are the PC game development challenges that led Andersson to ask for Mantle, and a discussion of how he thinks Mantle addresses those challenges. He goes into particular detail on the features of Battlefield 4™ that are optimized for AMD Radeon™ GPUs and how the game, along with the Frostbite 3 game engine, leverages Mantle to achieve a new level of PC gaming performance.
