The Maxwell line of GPUs are bringing immense GPU capabilities which neither OpenGL 4.4 nor DirectX 12 will be utilizing. Some of these GPUs will even feature embedded ARM cores. With the Maxwell GPUs we are close to eliminating the CPU overhead all together by moving all the rendering control to the GPU. In essense you can pass a single call to the GPU requesting a frame, then the GPU will detect which objects to render, fetch data if necessary, occlude excess objects, calculate LoD and complete the rendering. This is the direction we need to go in order to achieve greater performance (for 4k).
