I'm looking to buy an AMD card soon. Is there any UNOFFICIAL Dolphin build that supports Mantle? If not, can you contact someone to make one?

Access to Mantle's SDK is limited to a select group of developers right now, and Dolphin's team isn't one of them. Someone will probably fiddle with it eventually, after the public release.

AMD cards run fine as it is in Dolphin. It'll be too much work for too little improvement for anyone to make a backend of it for Dolphin

Also, from what I've heard DX12 will make MANTLE pretty much obsolete.

It's also exclusive to Windows 10. While the upgrade will be free for Windows 7 and 8 users for the first year, supporting Mantle would be helpful for people who miss that window.

There are no plans for DX12 or Mantle support since OpenGL and DX11 currently do a fine job of what we need. DX12 and Mantle are aimed at reducing driver overhead on the GPU, while Dolphin's main bottleneck comes from the CPU

And OpenGL already made Direct3D 12 obsolete. Go figure.

DX12 and Mantle aim to reduce the driver overhead for the graphics, which means they will lower the cpu load for graphics. Just look at those Mantle benchmarks with amd cpus. This would help when you are bottlenecked by the cpu.

But this discussion is pointless, there's still no public SDK for either of them, so nobody can do anything, even if somebody wanted to.

Dolphin wont benefit from Mantle in any noticeable way. From what I've read on Mantle, it helps scale the CPU load across multiple cores and increase multi-threaded performance. None of that matters since Dolphin is only a dual core program.

I didn't want to make a new thread for this, so I will revive this one.

There are some interesting news regarding new command buffer APIs:

1. Vulkan, previously known as glNext and "successor" of OpenGL for high performance graphics, is built upon Mantle. So is something like Mantle 2.0.

2. Microsoft has published DX12 in preview for W10. With very preliminary documentation: https://msdn.microsoft.com/en-us/library/dn903821(v=vs.85).aspx

3. Same goes for WDDM 2.0, Johan Andersson, lead programmer of Frostbite engine, said this would allow a big improvement not just for D3D12, but for Vulkan too: https://msdn.microsoft.com/en-us/library/windows/hardware/dn894184(v=vs.85).aspx

4. AMD released Mantle API Programming Guide and API Reference. I think it's worth checking out, knowing that most things will stay the same in Vulkan: http://www.amd.com/Documents/Mantle-Programming-Guide-and-API-Reference.pdf

5. Not purely related but Ben Vanik, worker at Google, has a Xbox 360 emulator project on the go: https://github.com/benvanik/xenia
What he and a few contributors have achieved in a couple of years is impressive: https://youtu.be/vE32Z9ytbgU
He seems pretty well informed about these new APIs and what they are capable of ,and he is gonna use them in Xenia.

Cheers.
