Anandtechs look at DX 12 in action with star swarm.

It doesn't matter if 290X is doing poorly with DX12 due to drivers or whatever. What matters is how well the next AMD cards will do and the big news AMD/Microsoft are rumoured to be announcing at Computex may well be that the 300 series are the leading cards in DX12 due to the huge bandwidth available..

Thinking about it logically you would expect AMD based systems to fly on DX12 purely on the basis it was written for Xbone and that console has AMD hardware inside, so logically speaking I would expect to see good performance out of DX12 on AMD hardware.
With that said, something in me says that AMD have something truly special and epic up their sleeves. The blatant ragging on Nvidia over the vram issue, their total lack of silence over leaked into etc, the canned responses of "putting the finishing touches on" etc.
I have a feeling 3xx series are going to be groundbreaking when coupled with DX12, infact it's almost like AMD are going to walk up and drop the gpu's off with a smug grin and a "Were just to leave these here" as they walk off and watch arms folded with Cheshire grins as people fire them up and their jaws hit the floor

If I have dx12 on windows 10, What happens when I load up dying light or crysis 3?
Does it use dx11 and will it be the same as it is now performance wise, Or does it use dx12 but in a dx11 compatibility mode and speeds dx11 games up?

With any luck. The GPU sector has been stagnant and boring for far too long.
No gain. They need to design and write things from the start to support DX12.

March 2014, 6 months before Maxwell was released, gratz on just making stuff up as per usual;
http://techreport.com/news/26210/directx-12-will-also-add-new-features-for-next-gen-gpus
as Nvidia's Tony Tamasi clarified in an interview with us today
Tamasi explained that DirectX 12 will introduce a set of new features in addition to the lower-level abstraction, and those features will require new hardware
this wasn't the only site to release the info but it is the only one I can be bothered to without trawling through google to find more
AMD have still not confirmed what level of support each of their generations of GCN will have for DX12, as far as I can find. So nvidia have been much more upfront, releasing this info the same month as the DX12 reveal, and not, as you fallaciously claim, after the GTX980 release.
Radeon 5870 would be 2 generation before the 7*** series then? or did the 6*** series just cease to exist in DM's world?
I dunno I mean direct x is backward compatible so who knows if any of the dx11 files are what we have now or updated slightly files which in turn may improve dx11 by a small nudge. As personally I doubt highly that in win 10 the dx12 set is just about dx12 files and features as they must have tweaked older DX 9 and 10 and 11 files while there doing 12. Maybe for fixes only but maybe it has a benefit for us in existing games.
I'd like to see benches of all DX 9 10 11 and 12 titles on win 10 and compare em to win7 when win10 is out.

I don't think you will see much if any impact upgrading to dx12 and playing dx11 titles. The game needs to be written from the ground up with dx12 commands to make full use of it.
The first full dx12 engines will be noticeably superior to dx11, look at mantle on bf4, that engine was never designed with mantle in mind, it was tacked on later but the results were decent, now imagine that engine being built from scratch with the api.
With dx12 though as I understand it, simply upgrading to dx12 will have negligible impact on current titles.

No one thinks tje chart is flawed showing a 750 ti within 5 fps of the gtx 980?
Or that a r9 290x gets 8.3 fps compared to the 750 ti's 21.7? The base numbers are wildly flawed and low thus any percentage increases can be disregarded aw equally flawed?

Nothing strange in 750 ti being within 5fps from 980 under dx11. As 750ti gets almost full performance under dx11, 980 is starved to death.
Same with 290x, which only shows how bad AMD dx11 drivers really are (especially on this test). All of their cards are hitting same framerate under dx11 (~8fps).
Remember this is RTS mode zoomed out, which gives you over 100000 batches most of the time.

Intetesting to see how mantle performs with different number of cores used. You can clearly see that small patch optimisation is working , thus giving some extra performance. Until you go down to 2 cores where there are no extra performance left for cpu to handle extra work.
I can verify this from my own tests in older version of starswarm. Using only 2 cores (even on 7970) won't give full 100% gpu usage in test when using small patch optimisation. It does give full usage with it turned off.
Why AMD is so much slower than nVidia in this test (remember 780Ti is also much faster)? Could it be because bad color or tesselation compared to nVidia's cards?

Nothing happens to 970, will work as many sites tested. I am happily gonna buy you 970 if u don't like the idea to run DX12 on it.
I keep my GTX 570 just to test DX12 improvements and see what % i can get extra.
Nvidia DX12 test result, i believe truly amazing, even if it is an alpha phase driver
No one knows yet, review partner sites haven't tested DX12 running on a
So you shouldn't be afraid at all what happens to it. Let them test it under DX12. End of story. It is a nice vga, i would buy it anytime. 970 doing excellent job in DX11 .
That 50% lead tells me something.
