These are old plans, they have nothing in common with what was actually done in WDDM 2.0, no reason to suspect that they relate to WDDM 2.1 either. Using compute tasks in the rendering pipeline is of no issue even on an older architectures like Fermi. Gameworks doesn't use Optix and only PhysX is using CUDA. There are no issues with running Gameworks on GPUs, even PhysX. There are no issues with scheduling compute into the graphics pipeline. You can take whatever you want. What you write clearly shows that you don't know anything. Intel's "most advanced GPU" have the exact same support for async compute as Kepler and AFAIK an even worse pre-emption granularity. As I've said, learn things before talking about them.
