TECHNOLOGY TRENDS

When Microsoft officially releases Windows 7 on October 22, 2009, they module be delivering to the world what they promised Windows Vista would be… with a few nifty extras, of course. So, you can’t blame some folks for skipping Windows Vista and hanging onto Windows XP while Microsoft gets Windows 7 working.

Beta testers have so far been very impressed with Windows 7. It’s fast and it’s stable. One of the reasons is the improved graphics capability in Windows 7. Microsoft seemed hesitant in utilizing the full capabilities of the graphics processor in Windows Vista, which was a real shame. Windows 7 changes all that, and that’s what we module be talking about today.

We recently got our hands on more internal documents on DirectX improvements in Windows 7, or rather how Windows 7 takes better advantage of Direct3D. Although Microsoft has publicly revealed some info on what’s improved, this document reveals the info on what’s improved, as well as the new Direct2D and Direct3D 11 APIs.

Windows 7 & Direct3D 10

The Direct3D 10 API that was free with Windows Vista was a rearchitecture and ground-up code rewrite of earlier Direct3D versions. Direct3D 10.1, which was free with Vista SP1, came with some incremental changes. Windows 7 further builds upon the Direct3D 10 infrastructure in the mass areas :

* Desktop Window Manager (DWM)
* Direct3D 10-level-9
* Remoting changes in Direct3D 10
