    Honestly I never expected to see mantle in Linux... for that matter, I don't expect to see mantle anywhere in the next few years.
    Besides, AMD has given us Freesync(just submitted, and apparently accepted by VESA) so one less place for proprietary solutions.

      Hmm... I am already using mantle on my gaming computer so yes, it is here. Both Battlefield 4 and Thief are running great with it and I got a few more FPS out of it. More importantly, the gaming experience feels a lot more smooth than with DirectX. (And yes, I have compared with both AMD and Nvidia cards).

      I love it, and I would love to have it come to Linux since both Cryengine and FrostBite do support mantle.

        Isn't that train of thought a bit weird? Disabling Catalyst AI by default is seriously just a "flip of the switch" type of effort from AMD's side. Wouldn't it make more sense if they, y'know, fixed the bugs that cause these graphical glitches in the first place? That's a bit more comparable to working on Mantle, effort-wise.

          Variable VBlank refresh is an eDisplayPort feature, AMD just called it something else and showed laptops using it. They did probably put enough pressure on VESA to get it in DP 1.2a, though.

          AMD so much so that they made their own friggin' API instead of just working inside OGL.
          I'd counter argue this saying "OpenGL is a massive bloated 25 year old mess" and that a really well architected modern stateless API for GPUs would be great, but only if it were an open standard, and Mantle isn't, so it can still piss off. GLES is kind of an attempt to remove some cruft, but it still uses an imperative C derived style in functions and shading that makes me feel like I'm in film grain in the 1980s.

            You also can look at OpenGL/OpenGLES with all its versions and extremely different performance behaviors (I call it the performance breaking minefield) on different vendor implementations as an enormous amount of different APIs that just use the same function names to raise the confusion.

            Why does Khronos even have Microsoft as board member? The worlds most determined enemy of OpenGL I can think of...

            DSA functions are still not a part of the core versions and the EXT version is not implemented by intel. It seems the us few users of such esoteric languages like C++ just don't matter that much.

            Oh and look at ARB_buffer_storage, the little cripple that got a hint stuck in its knee. Even the ARB specification has some wry humor about that... So you still stuck without knowing if you got VRAM, pinned memory or non pinned memory including all the random buffer moving by moody drivers.

            AMD continues with there multiple personality disorder that makes them change there mind every few months. Right now it looks like they want mantle to be a pre DX12 exclusively for there GCN GPUs and after DX12 let it die without ever open it to the public. But hey! Maybe in one month AMD tells us again about the all open for everyone Mantle API... who knows!?

              Isn't AMD currently adopting OGL4.4 and Nvidia's new OGL extensions?
              And aren't most big game engines moving to OGL?

              If so isn't Mantle a moot point at this point?

                AMD talked about upcoming Mantle games, and they had this interesting statement about Linux (emphasis mine): http://community.amd.com/community/a...are-on-the-way

This is terrific news because it really draws attention to the value of low-level programming and Mantle’s leading contribution. With DirectX 12 games still over 18 months away and no alternatives in sight for Linux gamers, Mantle’s future looks bright.
                If my interpretation is correct, this means that either Mantle or some other form of low-level programming will come to Linux.

                  But why is mantle not supported in the linux catalyst since 14.1? Why is it STILL not supported by linux catalyst? Why isn't there even a public specification? Not even public documentation. Not even a single line of example code?


                  Is it cynical to joke that we will probably have Direct3D 12 support in Mesa on linux before any mantle support?

                    what to make of this?

                    Does Richard Huddy have the clout to make this happen? Seems he recently rejoined AMD.
