No DX12 Support for Deus Ex: Mankind Divided at Launch
Over at its Steam page Eidos states that "Deus Ex: Mankind Divided," will not ship with DirectX 12 support at launch. The game will release on August 23, 2016 based on DirectX 11. DirectX 12 renderer will be added via a patch, which will release in the week of 5th September.
The Deus Ex franchise originated on PC, and we’re passionate about continuing to provide the best experience possible to our long-time fans and players on the PC.
Contrary to our previous announcement, Deus Ex: Mankind Divided, which is shipping on August 23rd, will unfortunately not support DirectX 12 at launch. We have some extra work and optimizations to do for DX12, and we need more time to ensure we deliver a compelling experience. Our teams are working hard to complete the final push required here though, and we expect to release DX12 support on the week of September 5th!
We thank you for your patience, passion, and support.

I wonder if the game was programmed on dx11 all the time and now being released, with a later adaption to dx12, or if they have to use some kind of 'container' to run it under dx12, crippling dx11 performance somehow.

A year ago I would have been disappointed at this news but having had the chance to compare DX11 and DX12 in the same games since then I've come to realise that DX12 offers absolutely NO visual improvements and usually runs slower than DX11, at least they did on my old GTX 980 Ti. Maybe things will be different on my new GTX 1080, which reputedly supports asynchronous compute, but I'm not holding my breath.
Yes, part of the problem here is that most games are not designed from the ground up for DX12 (as Deus Ex: Mankind Divided clearly isn't either) so that likely accounts for why performance is not quite as expected. However, when we went from DX8 to DX9, from DX9 to DX10 and DX10 to DX11 we got something in the way of graphical upgrades too (tessellation, better lighting, etc) but, so far, DX12 hasn't even given us that (which would at least make up for the loss of performance vs. DX11). Rise of the Tomb Raider actually loses the VXAO support I believe if you use DX12!

^Careful bad mouthing DX12 there.
So far we have not seen much in the way of a difference on Nvidia's side but that is likely down to how good their DX11 drivers were/are.

Obviously your DX12 experience is going to vary based on the type of card you have. Currently Nvidia doesn't get much out of DX12 - their driver had command list support and stuff. If you have an AMD card, you're probably going to want it a lot more because it brings a pretty massive boost to your cards.
That being said, DX12 overall does give developers the potential to increase graphics quality and performance across both vendors. So regardless to what some of the initial games perform, owners of Nvidia & AMD should both want DX12 to become mainstream.
Also, the reason why they'd develop a DX11 variant of the game is to open sales up to pre-windows 10 users, which is the majority of people at the moment. I doubt the DX12 delay was done for any real purpose other then it wasn't finished.

Why not. It's just that by lowering driver API overhead it can now use extra GPU power for more effects, objects, detail.. That's if done right.
