A chap from PCGamesHardware managed to find some interesting info that was mentioned during GDC and that has something to do with DirectX 11 porting. Johan Anderson, Rendering Architect at DICE, has revealed some interesting details about the Frostbite Engine, also known as the Battlefield game engine.

According to Anderson, porting the Frostbite Engine from DirectX 10 to DirectX 11 was done in three hours and searching and replacing the relevant parts inside the code was mostly the only thing that was required.

He continued that developers at DICE are certain that the CPU load during API calls can be reduced with DirectX 11 drivers. As they had no DirectX 11 hardware they had a switch inside the compiler that can be changed to DirectX 10 or DirectX 11. Among a bunch of other things, the FrostBite DirectX 11 engine offers HDR texture compression, Compute Shader and hardware tessellation for characters and terrain.

We hope that Nvidia or ATI might soon get some beta DirectX 11 capable hardware to DICE, so they can tell us if the DirectX 11 is as good as it looks.
