After last Wednesday's Windows 10 event, early adopters and IT types were probably anxious for Microsoft to release the next preview build. Fortunately, it didn't take long as it came out on Friday, and it's safe to say that it introduced even more than many were anticipating (but still no Spartan browser). However, in case you missed it, DirectX 12 is actually enabled in this Windows 10 release, though unfortunately we'll need to wait for graphics drivers and apps that support it, to take advantage of DX 12 features and performance enhancements.
