Translates D3D11 games to D3D12 using Microsoft's own D3D11On12 wrapper library.
Windows 10 build 1809 is required for this to work properly. Might work with 1803, but that was not tested.
Just download the latest release,
copy the d3d11.dll next to the executable of the game you want to run, and start the game.
Make sure to use the x64 one for 64-bit games, and the x86 one for 32-bit games.
If everything works correctly, you will most likely experience reduced performance compared to native D3D11, and in some cases rendering issues and/or driver crashes. Some games may refuse to run entirely.
Note: Tools like MSI Afterburner will still show D3D11 in their overlay. This is because they see a DXGI swap chain created for a D3D11 device, not the underlying D3D12 device.
Why not? Just don't expect any sort of support when running into issues.
