Poking around the fresh Windows 10 build last night, I found an interesting new feature that Joe Belfiore didn’t mentioned in his announcement post: DirectX 12 is already baked into the operating system for Windows 10. Install the Windows 10 Preview and run dxdiag.exe, then look for the DirectX Version Info at the bottom of the System tab. DirectX 12 is one of the key features Microsoft hopes will woo PC gamers—a stronghold of the PC ecosystem, but one largely encamped in Windows 7—towards Windows 10. Microsoft says DirectX 12 will sport a vastly better threading model than the five-year-old DirectX 11, giving developers more console-like “closer to the metal” access to graphics processors. In a nutshell, DirectX 12 can offer much improved performance and (Microsoft claims) up to 50 percent power savings under proper conditions. Microsoft has already said it plans to talk more about DirectX 12 at the Game Developers Conference in early March the same event that Valve plans to reveal more about its Steam Machines!—so I’d expect to see DirectX 12 drivers from Intel, AMD, and Nvidia by then at the very, very latest, especially considering that Microsoft already sneaked DirectX 12 itself into Windows 10. Until then, there’s plenty of fresh stuff in Windows 10 to keep you occupied. I’d suggest checking these 10 killer Windows 10 features out first after signing up for the Technical Preview. Microsoft at least clear a few questions regarding DirectX 12, which is due to be included in the company’s upcoming Windows 10. The next version of Graphics Software, DirectX 12 will be much better than its successors as reported by a company official, who is none other than the Xbox boss Phil Spencer during the Windows 10 event in Redmond. The main doubt regarding Windows 10 and DirectX 12 has always been the graphical features. The general idea had always been that individuals will have to upgrade their Graphics cards in order to enjoy DirectX 12. The reports suggest that the gamers will not be required to add to or replace their graphics card.
