3DMark API Overhead feature test now available!

DX11 vs. DX12 vs. Mantle

Quote:
Games make thousands of draw calls per frame, but each one creates performance-limiting overhead for the CPU. APIs with less overhead can handle more draw calls and produce richer visuals. The 3DMark API Overhead feature test is the world's first independent test for comparing the performance of DirectX 12, Mantle, and DirectX 11. See how many draw calls your PC can handle with each API before the frame rate drops below 30 fps

 It's now available as a free update to 3DMark.
