Directx 10.0

Vole prepares DirectX 10.1

Ringing the changes

THE VOLE hasn't even finished the DirectX 10 that is supposed to come early next year with Vista, and we are already starting to hear that there will be a new addition to the specification.

We don't have any specific idea what the new things inside the new Direct X 10.1 specs may be and we are well aware that the Vole can simply change its name to Direct X 10.a or something of a similar sort. That happened recently with Direct X 9.c which was supposed to be released as Direct X 9.1, but that was more of an Nvidia versus ATI specification fight.

It's funny though, as Direct X 10 looks quite ready and you can already play about with the Direct X 10 SDK beta. As Vista got postponed a few times, the DirectX chaps figured out a few things that they can change and fix. The Windows Graphic Foundation 2.0, or what we now know as Direct X 10, has been finalised for more than a few months now and there are no changes to those specs. It is a done deal.

That is why there will be a new one, but we don’t yet know what new stuff it will bring. µ

Well its not the DX10 SDK that out .. its the DX9c SDK with some DX10 samples , emulated via software .... not much good either ...

DX10 is not backward compatible .,, main reason being the introduction of unified shaders .. so unless ur card supports that ur system will run under software emulated dx10 mode ... which is not good at all ..

Can't wait for Vista ... but can't wait to avoid dx10 ...

I found out a short & precise article on DirectX 10

A few changes have been made to DirectInput in order to support the Xbox 360 controllers and peripherals. Essentially, XInput, the API used for the Xbox, was converted and now works on Windows. Apart from this and minor changes in DirectSound, the biggest changes involve Direct3D. Expanded memory and texture limits (up to 8192x8192 textures, from 2048x2048 in DX9) are just the beginning. The biggest improvements are a unified shader model, which will hopefully free developers from having to write separate code paths for ATI and NVIDIA hardware, and new features such as the Geometry Shader that can add complexity to a scene procedurally. The Geometry Shader is integrated into the drawing pipeline, and allows the programmer to take simple shapes (such as triangles or even points) and generate complex shapes around them.

Microsoft has been a big fan of procedurally-generated graphics, including features on the Xbox 360 to specifically handle these items. However, DirectX 10 goes far beyond these ideas and adds features that, according to the interview, can't easily be done on the next-generation of consoles:

The things that we had mentioned in terms of being able to do much more data generation inside the pipeline is something that can't be done well [on next-gen consoles], even though the consoles sort of have their unique capabilities. And then there are things like the integer instruction set that neither of the two console [graphics] processors have available.

The developers were asked if the fact that DirectX 10 will only be available on Windows Vista was merely a marketing decision. It turns out that there were actually some good technological reasons for this requirement, mostly involving Vista's new driver model, which takes some elements out of kernel mode and into user mode for greater stability. The developers admitted that games requiring DirectX 10 (and therefore Vista) are probably still a few years away, although Microsoft is going to get the ball rolling with their Halo 2 port.

Definitely in the long term there's a vision in how we think the applications and the runtime and the hardware need to work together. What we've done in Vista was to make some major changes to try to improve that. We've got a number of additional things we wanted to do over the next few years to try to make that even better, and it's just hard to say, "oh well we'll just retrofit all that into Windows XP." That kind of put us in this position of saying, do we really want to get all these big improvements, and what do we have to give up in order to do it?

This interview gives the reason y DX10 is not compatiable with Windows Xp, also ATI's & Nvidia's approach to DX10!!
