Futuremark has released the first application test via which PC users can measure the performance differences between DirectX 12, DirectX 11 and AMD’s Mantle API. Via this test, PC users can get an idea of the benefits they’ll be getting – on their particular PC system – from the CPU-side improvements of DirectX 12.
As Futuremark noted:
“The 3DMark API Overhead feature test measures API performance by making a steadily increasing number of draw calls. The result of the test is the maximum number of draw calls per second achieved by each API before the frame rate drops below 30 fps.”
This DX12 application test requires an up-to-date version of Windows 10 Technical Preview (build 10041 or later), 4 GB of system memory, and DirectX feature level 11_0 compatible hardware with at least at least 1 GB of graphics memory.
