DX12 'Emulator'?

  1. This may be a really stupid question (posed by ignorant person), but is there any prospect for a DX12 'emulator' for 3 year old systems which redistributes the graphics load among available cores? I imagine it would have to be in machine code for it to make any significant difference.

    Thoughts? Rumors?

    Thanks!

    Found some new information. The folks working on a GameCube/Wii emulator called Dolphin have implemented a DX12 backend running on DX11 GPUs with a fine result, +50% increase in frame rates (http://wccftech.com/dolphin-emulator-significant-performance-boost-dx12/ ). My guess is that this comes directly from the improvement in CPU utilization - and has NOTHING to do with GPU.

    This was confirmed by these tests from last year ( "But remember that DirectX 12 is about making the API more efficient so it can take better advantage of multi-core CPUs. It's not really about graphics cards. It's about exploiting more performance from CPUs so they don't bottleneck the GPU." http://www.pcworld.com/article/2900814/tested-directx-12s-potential-performance-leap-is-insane.html )

    Could an API patch provide similar improvement to DX10 cards? .... DX9??
