Do you need to play the first one beforehand (story wise) ?

That's an opengl 1.1 based renderer (~1997 technology).

Some profiling to know where the hotspots are would have been interesting.

Quoting: FUltraI think that the version equality will be there for a long time since it's the same version due to Minecraft being a Java application. Of course they could always try and force the XBOX version as the only version (guessing here that that version is not written in Java) but there is nothing that indicates that this is on the road map.

The mobile version written in C++ is being ported to Windows 10. There no plan for Linux.

Quoting: ShabbyXCompletely true. A few months ago some apparently famous guy was showing equal performance between vulkan opengl 4.5. Opengl is very powerful, it's just terribly used. Vulkan is just a more modern reimplemention of the same stuff as opengl.

The problem is that most of opengl engines are object-oriented where the rendering loop does look something like this

render()
{
    for entity in entities
    {
        glBindTexture(entity.texture);
        glBindFramebuffer(entity.framebuffer);
        glBindVertexBuffer(entity.vertexbuffer);
        glUseProgram(entity.program);
        glDepthFunc(entity.depth);
        ...

        glDraw(...);
    }
}

You will notice that there a lot a state changes done by the driver for every object. To avoid that, we need to get rid of OOP to make our engines data-oriented (not to be confused with data-driven which is a different thing) where you sort/pack data in the following order

framebuffers -> global states -> programs (shaders) -> textures -> vertex buffer

The rendering loop then looks like this

render()
{
    for framebuffer in framebuffers
    {
        glBindFramebuffer(framebuffer);

        for global in framebuffer.globals
        {
            glDepthFunc(global.depth);
            glEnable(...);

            for program in global.programs
            {
                glUseProgram​(program);

                for texture in program.textures
                {
                    glBindTexture(texture)

                    for vertexbuffer in texture.vertexbuffers
                    {
                        glBindBuffer(vertexbuffer);
                        glDraw(...);
                    }
                }
            }
        }
    }
}

Now, Vulkan has real advantages over OpenGL: Finer control over memory consumption, clean api, same api on mobile, less bloat (you only implement what you need), SPIR, ...

Would be really surprised if it's DooM, even the classic id software's games that are packaged with dosbox are not available on SteamOS.
