I thot DX11.1 should come with Shader Model 5.1 & DirectCompute 11.1?

[Stephen.]

I thought DX11.1 should come with Shader Model 5.1 & DirectCompute 11.1?

But this is not the case instade AMD Radeon 7970 claims DX11.1 bit it has Shader Model 5.0 & DirectCompute 11.
I thought for the full features of DX11.1 to function the hardware should have Shader Model 5.1 & DirectCompute 11.1
Previous gen DX10 and DX10.1 hardware had shader Model 4.0 & 4.1 respectively, so as DirectCompute 10 & 10.1 respectively.

Does that mean that the upcoming hardware has no significant deference with current gen hardware in terms of hardware in handling Dx11 & 11.1?

And does that mean that current gen hardware can handle DX11.1? every other key details in terms of handling Direct X are same. apart from the coming GPU are just faster in general,....

afaik dx 11.1 does not have any new shader instructions, so sm 5.0

afaik dx 11.1 does not have any new shader instructions, so sm 5.0

So does that mean that even current DX11 cards can run DX11.1, is this the same scenario as DX9 - 9c where all the hard ware that could run Dx9 ware capable of running dx9c?

 

[Over_Lord]

I'm happy actually. Won't make the DX11 card owners suddenly feel alienated.

Again a possibility MS are adding those features specifically which will be a part of next gen XBox GPU

 

[Athlon2K15]

The following functionality has been added in Direct3D 11.1.


•Shader tracing
•Direct3D device sharing
•Check support of new Direct3D 11.1 features and formats
•Create larger constant buffers than a shader can access
•Use logical operations in a render target
•Force the sample count to create a rasterizer state
•Process video resources with shaders
•Change subresources with new copy options
•Discard resources and resource views
•Support a larger number of UAVs
•Bind a subrange of a constant buffer to a shader
•Retrieve the subrange of a constant buffer that is bound to a shader
•Clear all or part of a resource view
•Map SRVs of dynamic buffers with NO_OVERWRITE
•Use UAVs at every pipeline stage

How so? can Current Direct X 11 cards run Direct X 11.1?

Will this work on current gen GPUs?

Doubt it. And it wasn't the case that all DX9 cards could runs DX 9.0c content. I couldn't play BioShock on my x800, because it was missing shader model 3.0. I had to get some 3rd party patch to disable the SM3.0 stuff to be able to play it (although I later upgraded to an HD 3850 that beasted it just fine).

Ok not all coz of the deference in shader model, but i meant with the ones that had a card with SM3 or SM4 and had DX9c, even SM2 could ran DX9c.

So i mean since every other details are same in the sense of eg SM5.0 can run DX11 or DX11.1 if so then current hardware can run DX11.1

 

[Maban]

I've heard that current DX11 cards might support DX11.1. Sort of how OpenGL support increases with drivers (up to a point). But yes, as far I know it will stay at SM5.0. Don't know about DirectCompute though.
