GPU support of DX11.1 vs. DX11.2

[Gordon.C]

Hi,

I have been noticing that support for DX11.1 and DX11.2 varies by GPU model however in a quite confusing fashion.

GTX TITAN - 11.1
GTX 780 - 11.1 (some even 11.0)
GTX 780 Ti - 11.2

R9 290X with stock cooler - 11.2
R9 290X with upgraded cooler - 11.1
R9 280X some 11.1 some 11.2 no pattern
R7 270 - 11.2 for comparison

Most importantly, what is going to be the real life difference? I cant say there has been much of obvious changes since DX9a.

And who decides which GPU will support which DX?

Tessellation and displacement mapping are the 2 biggest changes. I believe even some of the newer lighting systems.

Once they start to actually use all DX11 has to offer then you will see the difference between DX9 and DX11. Right now the developers are just CJin each other.
