At the Windows 10 keynote, Microsoft showcased a benchmark to demonstrate how DirectX 12 allows developers to add complexity to a scene without frame rate grinding to a halt, compared to DirectX 11.
Of course, watching a video isn’t the same thing as actually testing it for yourself, but you shouldn’t worry, as you will indeed be able to.
Futuremark is going to release that benchmark publicly as part of its 3DMark suite. Not only you’ll be able to test DirextX 12 against DirectX 11, but also against AMD’s own API, Mantle, thanks to the API Overhead Feature Test.
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.
If you’re not familiar with the test, a “draw call” is basically an element (object, material, shader, and so forth) rendered in a scene.
The new test is marked as “coming soon,” and no precise release date has been provided.
In order to get your hands on it, might have to purchase 3DMark, which is available on Steam for $25. It hasn’t been mentioned, in fact, if the test will ever be made available as part of the free 3DMark Basic Edition.
