I downloaded and installed the DirectX 11 upgrade for Windows 7. Seems to work fine, I noticed it probably gave a bit of extra spice to my beloved one, the game Freelancer, Freelancer (video game) - Wikipedia, the free encyclopedia, the game originally being DirectX 8, or 9.

And HI ALL INFLUENTIAL FRIENDS HERE, going off topic: Came to think that the Freelancer community has hungered for the source code for this MICROSOFT game for years. No sequel is apparent, by Microsoft, but there's a heck of a lot of people willing to work on the project. And the game is well worth to be worked with. Being in good stand with Microsoft, you might be able to give a helping hand? It's really a win-win situation. :)
