We only ported the D3D12 runtime to Windows 7. The development guidance document for how to move DX12 to Windows 7 actually contains some useful information on how difficult it is to get games running under the older OS and what the differences are between the two. To better support game developers at larger scales, we are publishing the following resources to allow game developers to run their DirectX 12 games on Windows 7.
We have received warm welcome from the gaming community, and we continued to work with several game studios to further evaluate this work.
