Battlefield’s Frostbite Engine already ported to DirectX 11

Johan Anderson, Rendering Architect at DICE, revealed some details about the Frostbite Engine, which is the base for the Battlefield games. 
At the beginning of the porting progress the developer had to face a cross platform engine (PC, Xbox 360, PS3) with an exclusive DirectX 10 rendering path that had DX 10.0 and DX 10.1 features. The actual port of the Engine from DirectX 10 to DirectX 11 was done in three hours said Anderson. Searching and replacing the relevant parts inside the code required the most time. 

Since currently there is no DirectX 11 hardware or appropriate development software, the Frostbite Engine was equipped with a switch inside the compiler that can be changed to DirectX 10 or DirectX 11. The developers at DICE are certain that the CPU load during API calls can be reduced noticeably with DirectX 11 drivers. Among other things the Frostbite DirectX 11 Engine offers HDR texture compression, Compute Shader and hardware tessellation for characters and terrain. 

With Battlefield: Bad Company 2 and Battlefield 1943 there are two more games of the Battlefield series are based on the Frostbite Engine.
