When its characteristics were drown, DirectX 10 was extremely promising, in a degree that it would, again, change the way software developers aboard real time 3D programming. Not only would the graphic cards be given the possibility to directly calculate the shaders per pixel, the developers would have had the possibility to relieve the processor of useless calculus, that could have been taken over, with the help of DirectX 10 of course, by the GPU, fact that would have led us to new horizons in terms of graphics. ( the complexity and possibilities of a GPU have reached and i some cases surpassed the possibilities of a classic PC microprocessor ).

For example, with the help of adequate video card, many of the details simulated through software could be “worked” more directly by the video card, leading to a greater productivity and efficiency of the system.

There could be a lot of great stuff that could be accomplished and processed by the ability of the GPU, through complex geometrical operations. We could see particle systems, fine detailed models, i.e. grass or animal fur, that could change their position according to external factors, i.e. wind, sun, storm etc , basically procedural geometry for dynamic applications. These features could be available sooner or later, being influenced and limited by the hardware’s capabilities , when it comes to the issues of implementing these features promised by DirectX 10.

Alas! Concrete improvements already exist right in this moment, brought by the latest Microsoft Corporation API. It has been managed, in a certain degree, the reduction of the processors loadspeed, fact that can be sensed in the systems performances, detail that can lead to a broader and complex scene or environment in graphic applications.

All-in-All DirectX 10 offers programmers the possibility to concentrate on more punctual objectives, when it comes to hardware, but at this hour developers are limited by the shaders length and are affected by the rest of hardware equipment. There will exist a bloom of the DirectX 10 applications, once the rest of the hardware components develop as well (memory, motherboard etc).

For the moment many of the features present in DirectX 10 could have been easily implemented in the previous version, DirectX 9 and the new features don’t really bring anything spectacular from we could have gotten from the previous version of AP .

In present, the reality is the games that will be released in the future years will come with a full compatibility for DirectX9, the chance for DirectX 10 to make a name for themselfs, would be to have certain applications that run only on it, for example the latest/future generation of games. O the other hand, the launching in this moment of a game fully compatible with DirectX 10, alongside the insistences on the effects and advantages that it proposes could mean the suicide for any game producer ( except possibly Microsoft ). The main reasons is that, in this moment, as it will be in the near future, the majority of users still use DirectX 9 platforms, and another reason would be that most users hesitate to use a DirectX 10 platform which isn’t fully matured and that doen’t have that certain “stickiness” to the public.

As a particular and exclusive development of DirectX 10 applications is out of the question, it seems that the porting of games from DirectX 9 to DirextX 10 isn’t possible, for the simple fact the producers don’t wish to spend money/time on it,as the users don’t require it. As soon as the users request it, conversions will start.

For now, at high resolutions, of over 2560×1600 even the most powerfull video cards on the market ( like NV 8800 Ultra, GTX , ATI HD 2900XT) are completely outdone ( a resolution that would be absolutely necessary for a 30″ display i.e. ) so we can’t even take in consideration thinking of DirectX 10 entry-level or mid-level cards that would be compatible with it and unfortunately these are the only products available at a reasonable price 150 USD ( ATI HD 2400, NV 8600GT) or 250 USD (ATI HD 2600, NV 8800GTS).

To sum it up, the high priced and performant video card addicts are to few in numbers to be taken in consideration by the leading gaming producers. (source : Anandtech )
