We got a nice contribution from somebody, so we are going to use it to start this bounty.
We can really do with a more fleshed out Direct3D driver for RetroArch, so for this bounty we are looking for somebody who can add a Direct3D 11/12 codepath to the currently existing Direct3D driver.

Bounty starts out right now at $25. I will chip in some more shortly.
