EA-DICE' upcoming online shooter Battlefield 4 will take advantage of DirectX 11.1 API, on PCs running Windows 8 and Windows 8.1. Running the game with DirectX 11.1 will have a positive performance impact compared to running it on DirectX 11.0, or on older operating systems like Windows 7 (which doesn't support DirectX 11.1). In the words of the technical director behind Frostbite, the underlying engine for Battlefield 4, "We use DX11.1, there are some optimizations in it (constant buffer offsets, dynamic buffers as SRVs) that we got in to the the API that improves CPU performance in our rendering when one runs with DX11.1." This could give Radeon HD 7000 series GPUs an edge over their GeForce competitors. GPUs based on NVIDIA's "Kepler" micro-architecture don't fully support DirectX 11.1. Incidentally, Battlefield 4 was just bagged and tagged by AMD for its future "Never Settle" bundle. Join the dots.
