Speaking at the Game Developers Conference in San Francisco, Microsoft developers said the upcoming DirectX 12 API can deliver a 20 percent higher frame rate in games plus a drop in CPU utilization. It seems PC gamers will have a strong reason to upgrade to Microsoft's Windows 10 operating system.
McMullen used the same Intel "Asteroids" benchmark in his presentation Wednesday, but demonstrated that the frame rate increased a more modest 20 percent. But the CPU consumption also fell from 25 percent to 9 percent as DirectX 12 asked the GPU to shoulder more of the workload.
The demonstration ran on an Intel Core i7 4770R (with Iris Pro graphics 5200 installed), but McMullen didn't indicate whether Nvidia cards, for example, would see a greater improvement than hardware for AMD. The overall message was a simple one, however: if you're a gamer, you'll want to upgrade to Windows 10 and DirectX 12.
