G'day all,

On the subject matter, below from the vendor site pages.

NV_______DirectX______OpenGL
Titan Black__11.2________4.3
780 Ti______11 _________4.4
Titan_______11 _________4.3

AMD
R9 290X____11.2________4.3
R9 280X____11.2________4.3

I am no expert on the matter by any means so don't know what HW level capability really means and how 'bad' SW level emulation can be- if at all.

This is simply a fact checking exercise and would appreciate input in earnest.

If it is a matter of page details being incorrect or out of date, then would appreciate current capability advice as well.

Thanks everyone.​

You are far from the only one confused by the terminology of how Kepler supports DX11 (yes), 11.1 (supports the most interesting parts but not all of them) and 11.2 (yes). The Titan, Titan Black and 780 Ti all use Kepler.

homerdog on forum.beyond3d.com said:
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 evilsofa

Very interesting thread link and a fair bit to take in.
I need to understanding this tiering business of feature support.
Another thing being what is 'more' comprehensive/inclusive on a feature and implementation level. DX11, 11.1 or 11.2?
I have been sitting on a Win 8 license for a few months now. Given that 7 does not have 11.2, might have to consider taking the unwanted plunge:(

I find it interesting that none of the GPU-Z screenshots, even those posted very recently say any more than DX11 on the home screen for 780 Ti or Titan. I wonder what prompts that assessment.

Would also like to know where OGL 4.4 stands in its support @ a HW level on these current flagships.
 
According to Wikipedia's List of games with DirectX 11 support, the list of games that support DX 11.1 is:

Battlefield 4
Star Trek Online

Maybe there's more that I don't know about. It is apparently too soon for games to support DX 11.2 yet.

When looking for what effect fully supporting 11.1 has on BF4, I see talk that systems with AMD cards might get a bit better CPU performance than those with Nvidia cards.

My point being, it's not clear to me that missing those four optional DX 11.1 extensions will ever be of any importance whatsoever. I'd be willing to hear evidence otherwise.
 
I cannot recall a single recent gaming announcement that has touted DX11.2 as being the standout implementation.
Given the frighteningly long list of game engines (past and present), http://en.wikipedia.org/wiki/List_of_game_engines
...I doubt a critical mass could ever be achieved to justify extensive resource allocation to develop the 'complete' feature set of any established API, before it is superseded anyway.
