Microsoft ports DirectX 12 to Windows 7, giving some older PC games a performance boost

Just in time for Windows 7 to die, Microsoft is porting DirectX 12 to it -- on a game-by-game basis. The first game to deliver will be World of Warcraft, with others to follow. Microsoft's latest graphics API has actually been around since 2015. But Microsoft typically reserved its latest features for Windows 10, the latest OS that already demands the latest hardware. DirectX 12's support for multithreading, for example, already generates "substantial framerate impriovement," Microsoft says.
