D3DConfig: A new tool to manage DirectX Control Panel settings

In case game developers are limited on how frequently they can upgrade Windows 10 on their dev machines, they can use VHD files to quickly set up a new Windows 10 OS partition and to access new or preview features from DirectX 12.

New in D3D12 – background shader optimizations
Avatar April 16, 2019 Apr 16, 2019 04/16/19
tl;dr; In the next update to Windows, codenamed 19H1, D3D12 will allow drivers to use idle priority background CPU threads to dynamically recompile shader programs. This can improve GPU performance by specializing shader code to better match details of the hardware it is running on and/or the context in which it is being used. Developers don...
