Now the full documentation has been released from AMD regarding Mantle is their plans to implement this into Unity?
this question has maybe been asked, but i will ask again,
if i have not posted this in the right section can someone move it too the right section.
my first post so YEE HAA
Don’t think so, even AMD gave up partly on Mantle cause of Vulcan which will be supported in Unity
EDIT that’s what i found with a quick search on google, i’m sure if i delved in further i would find more information, correct me if i’m wrong but both the XB1 and PS4 both contain 7 series AMD gfx, which are supposed to be DX12, but as far as i know all AMD 7 series and R9s are capable of DX11, DX12 and Mantle,
The upcoming AMD Rx300 series is the first one designed for DirectX 12. The current Rx200 series is designed for 11.2 but supports 12. The HD 7000 series, which is what I believe you mean by 7 series, is 11.2 but only partially supports 12.
All I’ve seen is a Unity blog post stating that they’re working on making directx 12 available in Unity before Windows 10 gets released (trying at least). Not sure about Mantle or Vulcan. From what I heard though, Mantle is no longer going to be used in and of itself. It’s going to be a part of other API’s though – like Vulcan.
I forget what goodies directx 12 is bringing us though. I don’t know if it’s going to essentially be like Mantle or not?
*oh and grats on 2 posts bacon! Haha. I wish you many more successful posting journeys.
It makes more sense to focus on DX12 instead of splitting the efforts with Mantle. The only case where Mantle would have an advantage is with a Windows 7/8/8.1 computer running an AMD GPU, because there would not be DX12 support in those computers yet there would be Mantle support. So short term, Mantle support could be somewhat useful. But longer term, DX12 is what everybody is going to move toward. (users and developers)
DirectX 12 sounds great and works on Nvidia and AMD GPU’s but there is also Vulkan the OpenGL version of Mantle, and Unity already have a working build to IOS’s Metal API.
Note that Vulkan will not be limited to Windows 10.
Those platforms can simply use Vulkan though. Mantle’s only likely use, if it even works on them, will be the consoles.
it would certainly be nice too see Mantle and the other variants being picked up by the opensource community and used through Linux and other BSD variants to create a more stable gfx eco system, i’m not sure if that makes any sense,
please excuse my spelling and grammer, it’s hard to be me 
It already is it’s called Vulkan the new OpenGL graphics api.
