Oh, sorry for the misunderstanding.

[quote name='http://www.dailytech.com/article.aspx?newsid=9656']When asked about the advantages of picking up a DirectX 10 graphics adaptor today, versus waiting for NVIDIA or AMD DirectX 10.1 products, Microsoft's senior global director of Microsoft games on Windows, Kevin Unangst, replied, "DX10.1 is an incremental update that wonít affect any games or gamers in the near future."
Microsoft isn't the only developer downplaying DirectX 10.1. Cevat Yerli, CEO of Crytek, states, "We pride ourselves on being the first to adopt any important new technology that can improve our games so you would expect us to get with DX10.1 right away but we've looked at it and there's just nothing in it important enough to make it needed. So we have no plans to use it at all, not even in the future."
NVIDIA's latest guidance describes DirectX 10.1 as "a minor extension of DirectX 10 that makes a few optional features in DirectX 10 mandatory."[/quote]

DX10.1 does not make DX10 obsolete, and it doesnít make the hardware obsolete. 10.1 is the improvement on the API. Because DX10 was a little loose with the guidelines, 10.1 makes absolutely no compromises anymore. Microsoft made the spec to support the hardware manufacturers back then because of development times and SDK, so people could start developing for Vista. If a game absolutely requires 10.1, which no game will do because it would be economically a ridiculous call - if you were to make a DX10 only game, it would be 10 only, not 10.1. Otherwise, youíd rule out a whole generation of DX10 hardware.
The features that it supports are not critical. The difference is so minimal. You would have to have two more generations of graphics hardware to really consider making a DX10.1 only game where the [DX10.1] features then would become significant if actually used right. I didnít look at 10.1 because for me, I just looked at our engineers and said, ďNo, donít need it in the next 12 months.Ē (laughs) Thatís all I need to know right now.
From what I understand, even if you had the next generation of 10.1 hardware, it would be too slow to use the features. You would have to wait two more generations in order to get a real benefit from it. Remember, Matrix introduced environmental bump mapping almost 6-7 years ago? Normal Mapping and bump mapping just made it in the four years since then. In fact, Far Cry was the first normal mapped game to ship. When you look at it this way, itís the same as 10.1. 10.1 will become actual or three years from now. But not now.[/quote]
