In this case, Nvidia has only software support for DX11.1. The hardware isn't built for DX11.1, so the DX11.1 code that it does run is, theoretically at least, less efficient. The article, or a least a quote from the article, does say that "90% of differences between 11.0 and 11.1 are software anyways" (even though it looks like it's actually 60%). But one has to wonder if that code would run better if the hardware was tuned for it. However, there's no telling that GCN is optimized for the "software-level" DX11.1 features.
I do think that Nvidia's statement that these aren't gaming features is total bull. The last two definitely sound like they're useful for 3D gaming, and for the former two, whoever said that 2D rendering can't be used for games?
It also would have been nice for Nvidia to have clarified Kepler's DX11.1 support at launch, rather than playing dumb. It's disingenuous at best.
