What are your opinions on DX12/Vulkan/Mantle?

I'm pretty torn on what to think about it. On one hand being able to write the implementations for a lot of the resource management and command processing allows for a lot of gains, and for a much better management of the rendering across a lot of hardware. Also all the threading support is going to be fantastic. But on the other hand, accepting that burden will vastly increase the cost to maintain a platform and the amount of time to fully port. I understand that a lot of it can be ported piece by piece, but it seems like the amount of time necessary to even meet the performance of, say, dx12 is on the order of man weeks. I feel like to fully support these APIs I need to almost abandon the previous APIs support in my engine since the veil is so much thinner, otherwise I'll just end up adding the same amount of abstraction that DX11 does already, kind of defeating the point. What are your opinions?

Just for laughs...

Don't know how much is old this page on Mantle manual, but the DX SDK page was there when I joined to the DX12 EAP on October 2014..

Anyway looking at the early private DX12 EAP docs the D3D12 API has changed a lot from it announcement to the current public version..

I'm in both the Mantle beta program and the DX12 EAP, the mantle documentation has been around for quite a bit longer as far as I'm aware.

I gets all your texture budgets!

Apple has announced their upcoming OS X version El Capitan. Thought that it would be relevant to this thread, as it will bring support for their Metal API to OS X.

I have no details, but apparently there has been claims of 50 % improvement in performance and 40 % reduction in CPU usage.
