DirectX 11 is creating a lot of buzz these days, with ATI leading the way over Nvidia by the first one’s to release DirectX 11 graphic cards( 5850 and 5870 to name a few) including the fastest 5970.So why go for directX 11 cards ? How can be made use of ? Coz the future is DirectX 11 for gaming and  crystal clear HD picture quality.DirectX 11 can be made use of in Windows 7 as it comes with it while Vista comes with DirectX 10.1.To gloss over the advancements in DirectX 11, Microsoft has released the following features explanations:

• Tessellation – Tessellation is implemented on the GPU to calculate a smoother curved surface resulting in more graphically detailed images, including more lifelike characters in the gaming worlds that you explore.
• Multi-Threading – The ability to scale across multi-core CPUs will enable developers to take greater advantage of the power within multi-core CPUs. This results in faster framerates for games, while still supporting the increased visual detailing.
• DirectCompute – Developers can utilize the power of discrete graphics cards to accelerate both gaming and non-gaming applications. This improves graphics, while also enabling players to accelerate everyday tasks, like video editing, on their Windows 7 PC.

Tessellation

What does Tessellation mean actually ? Tessellation is probably the most significant change in the new DirectX. For those who like realistic looking characters and terrain, tessellation will be king. Basically, it will allow programmers to use more detail in developing game characters and environments. It’s like a transition from normal definition to high definition.

Multi-threading

As this was doing good for programs in Windows 7 this will do good for games too.With the invent of multi core processors and core i7 these can make use of multi threading and multiprocessing capabality. Multi-threading will allow us to take full-advantage of the power within each core, thereby allowing programmers to create more-detailed environments without sacrificing FPS.

DirectCompute

Direct compute will allow programmers to take advantage of the processing power of the graphics GPU. The best way to put this as explained from David Patterson’s presentation where he explained, “You have a book and a software program designed to count the number of times a certain word is used in that book. Run that program on a CPU (a serial/sequential processor) and it would start on page 1, read the entire book word-by-word, page-by-page until it finished and eventually give you an answer. Give that same problem to a GPU (a parallel processor) that supports DirectCompute and it would tear that book into thousands of pieces, and read through all of them simultaneously.”
