If AMD has been working with MS on this, is it fair to assume NV has also been optimizing, and what about intel?

This is for all GCN based cards according to the source. So HD7000 and on...

Ok. Got it. Tks.
So, backward compatibility with older gen cards (assuming Fiji is the new gen). But, NV is not supporting DX12 optimizations on cards older than Maxwell, is that correct?

Looks like Kepler supports it but not as well as the newer cards.

Do you really think AMD would open up DX12 to 7000 series and up though?

I don't see them doing that. New DX versions are almost ALWAYS used to sell more cards.

Is it bad that I am still skeptical about it though? smile.gif

That seems like a silly move to me.

If true though, it looks like my 7950 and I are moving on up to Win10!

I think it's mainly because DirectX12 is built very similar to Mantle.

Well architecturally the 7000 series is almost similar to amd r9 2** and r7 2** series. So, if the later is compatiable then there is no reason that the 7000 series shouldn't be compatiable. Also, even in the worst case senario the software part can easily be ported from r9 & r7 series easily.

But, the catch here would be, how much would that be compatiable with dx12. I don't see that 100% compatibility can be implemented. It's just that, you would get better performace in specific scenarois with 7000 series. But, with newer cards that won't be a problem.

I wouldn't be surprised if "full support" required newer cards.
