NVIDIA Kepler not fully compliant with DirectX 11.1
After a discussion on a German a website, NVIDIA confirmed that the Geforce 600 series does not fully support DirectX 11.1 aka is 100% compatible. Well, it doesn't fully support the API. The GTX 680 supports DirectX 11.1 with hardware API eature level 11.0, including all optional features.
Now that does include a number of features useful for game developers such as ...
Reply directly from NVIDIA:
- Partial constant buffer updates
- Logic operations in the Output Merger
- 16bpp rendering
- UAV-only rendering
- Partial clears
- Large constant buffers
We did not enable four non-gaming features in Hardware in Kepler (for 11_1):
- Target-Independent Rasterization (2D rendering only)
- 16xMSAA Rasterization (2D rendering only)
- Orthogonal Line Rendering Mode
- UAV in non-pixel-shader stages
So basically, NVIDIA does support 11.1 features with 11_0 feature level through the DirectX 11.1 API.
"We do not support feature level 11_1. This is a bit confusing, due to Microsoft naming. So we do support 11.1 from a feature level for gaming related features."
The competitions AMD's Radeon HD 7000 "Southern Islands" GPU series is fully compliant with DirectX 11.1 (except the rebranded products from the 6000 family).

Bro AMD is far from dying. AMD chips are what is going into all of the next gen consoles. AMD A10 APU in PS Orbis etc.
If they were in danger of dying as a company, Microsoft, Nintendo, and Sony would not all 3 go to them for their chips....
Even if it gets to the point where they cant sustain themselves anymore, a company will surely grab them up, you can count on that.
We will still have Radeon and AMD CPU's for a good long time yet.
Although they may one day in the not so near future, refine their APU's to the point where they can just sell those and yield great performance.
Spouting crap like AMD is dying is just rubbish. Name change one day? Maybe.
AMD is running out of money. Most of us consider that "dying"....

Absolutely not an issue whatsoever! Firstly, DX11.1 is useless in a practical sense; plus, if Windows 8 is out of the picture, it doesn't even matter because the DX11.1 "patch" for Windows 7 is fully supported by the Kepler architecture. In any case, all's good nvidia, just keep the kick-ass drivers coming!

These unsupported features seem to only concern some future professional applications - I'm pretty much sure they'll want to use that to differentiate cards between gamer GeForce and workstation Quadro / Tesla.
