DirectX 12 Ultimate Getting Started Guide
So, you’re a developer sold on the next-gen features in DirectX 12 Ultimate?
Look no further than this little guide!
The complete set of DirectX 12 Ultimate features is be available in the next retail version of Windows 10, version 2004 (also called the Windows 10 May 2020 Update).
As of 5/27, you can get this version of Windows by following these instructions. This is recommended for most developers.
We also wrote a handy guide on how a developer can use a VHD (Virtual Hard Disk) for DirectX development. Using a VHD allows setting up temporary OS versions to test new features on, which can then easily be thrown away or replaced as needed, kind of like the PC equivalent of an Xbox devkit.
2) Visual Studio
Once you have the latest Windows 10 build, install Visual Studio 2019 onto it (Note that the free Community Edition will work if you don’t already have the Professional or Enterprise editions)
3) Windows 10 SDK, version 2004
Download and install the Windows 10 SDK, version 2004. You can download it here or by selecting “Windows 10 SDK (10.0.19041.0)” in the optional components of the Visual Studio 2019 Installer.
This SDK provides headers for all the DirectX 12 Ultimate features, and also the latest version of the HLSL shader compiler, dxc.exe.
4) Drivers and hardware
Today, you can get started developing with DirectX 12 Ultimate features with NVIDIA GeForce 20 Series hardware.
- Developers who want a preview driver with support for Sampler Feedback, Mesh Shaders and DXR 1.1 should go here: https://developer.nvidia.com/directx
- Release drivers 430.39 and above already have support for VRS
- Release drivers 416.16 and above already have support for DXR 1.0
We’ll also update this part of the guide once more DirectX 12 Ultimate hardware is publicly available.
The March 2020 release of PIX has initial support for DirectX 12 Ultimate features – go here to download our very own DirectX 12 debugger.
We’re constantly adding features to PIX so be sure to check out the PIX blog to get the latest.
Check out the DirectX 12 Samples Repo to see samples of DirectX 12 Ultimate features.
We’ll be updating this repo with more samples over time, but we already have samples for VRS, DXR 1.0 and Mesh Shaders to get you started!
The DirectX Spec Repo is where we publish our specs; head here to find the specs for DXR 1.0 and DXR 1.1, Variable Rate Shading, Mesh Shaders and Sampler Feedback

I want to start developing with this except I don’t know where to find the 450.56 driver. I setup a 20H1 build and ran Windows Update thinking that would do it, but it didn’t. Any suggestions? Thanks.
EDIT: nvm, I saw a comment in Discord that you’re working to get the driver out!
download this driver and upgrade window 10 version 2004 and search box DXDIAG see your which direct x feature level and your direct x showing feature level12_1 so this is dx12 maybe feature level showing 12_2 is direct x ultimate.
