DirectX Nvidia confusion

[PearlJammer]

I was wondering if people with windows 8 and a dx11.1 card can check something for me. Using windoes 8.0 and a gtx780 the system information in the Nvidia Control Panel shows my DirectX runtime version as 11.0. Its not supposed to say 11.1? API version says 11.1 but not runtime. Thanks everyone

Your card supports DX 11.1 feature level 11.0. If you wish to see if your system supports DX 11.1 in windows 8, press winkey+r type dxdiag and see under display tab which DX version(s) your system supports.

There are 14 pages of confusion about 11.1 and 11.2 support in this forum thread:

In the last page, there's a post that seems to explain Nvidia's 600 and 700 series support best:

Kepler enables all 11.1 features except:

- Target-Independent Rasterization (2D-Rendering)
- 16xMSAA Rasterization (2D-Rendering)
- Orthogonal Line Rendering Mode
- UAV in non-pixel-shader stages

Kepler fully supports DX11.2 feature set. I believe it is level/tier 1, but in Microsoft vernacular that is still full support. Hell, MS used a gf770 in the DX11.2 announcement demo.

Thanks guys. So everyone would have the runtime show as 11.0 as well then?

yeh in a perfect world when someone says dx11.1/.2 fully supported it would mean fully not just majority, but I suppose this is no different then other companies calling their processors 8 cores when they are not they just have the majority of what would make up full cores, or for that matter big fast food saying 100% beef which just means that even if that paddie is only 1% meat, that meat is 100% beef, its ok to lie/fib if no one holds you to it of course.

Nvidia makes their own rules period, has been this way for decades, and folks just buy them up left right and center, even if they pay dearly for it in more ways then one XD

These are Microsoft's 'rules', not NVIDIA's.

AMD, Intel, Nvidia etc all have a certain amount of say when it comes to the new DX versions as well as their features, MSFT may implement it but they rely on feedback from the industry at large otherwise it would not make a lick of sense. Take tessellation for example, only supported after Nvidia and Intel agreed they were ready to support it.

Anyways, Nvidia makes its own rules, TWIMTBP is a pristine example of this, as is the experience program or Nvidia game works program, PhysX etc the more they are supported, the more they shaft user and developer alike.

Intel/AMD have their own counterparts. So I guess everyone is giving everyone the shaft.
