The new teaser video from Microsoft, which includes footage from various DirectX 12 titles like the Deus Ex: Mankind Divided, Forza Motorsport 6: Apex, Quantum Break, Gears of War: Ultimate Edition, Just Cause 3 and the earlier seen Ashes of the Singularity, which allowed the explicit multi-GPU support to be tested. 

According to Microsoft, the DirectX 12 will bring up to 20 percent more GPU performance up to 50 percent in overall CPU usage, compared to the DirectX 11. The video starts with an impressive quality difference between two APIs, especially when it comes to lighting, touting an unparalleled graphics fidelity. 

Microsoft also claims that the DirectX 12 has the fastest API adoption this decade. 

Some of the first games launched with DirectX 12 support, like the recent Gears of War: Ultimate Edition, had seen a lot of problems, especially on AMD Radeon graphics cards, and simply show that both developers as well as graphics card makers have a lot to do before we seen those promised performance improvements. At least the video from Microsoft looks impressive.
