D3DConfig: A new tool to manage DirectX Control Panel settings
D3DConfig: A new tool to manage DirectX Control Panel settings
The DirectX Control Panel (DXCpl.exe) has dutifully given developers the ability to configure Direct3D debug settings for nearly two decades.  But what started as a simple utility for controlling D3D debug output and driver type selection has struggled to keep up with modern DX12 debugging options.  In addition, the UI-based DXCpl doesn’t

New in D3D12 – Motion Estimation
In the Windows 10 May 2019 Update, codenamed 19H1, D3D12 has added a new Motion Estimation feature to D3D12. Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another. Motion estimation is an essential part of video encoding and can be used in frame rate conversion algorithms.

Use VHD to Accelerate DirectX 12 Development
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.

We’re going to use our Discord channel in the same way as our directxtech.com forums, which means that game developers will still have a great resource to get their DirectX12 questions answered, file bug reports, and to give
Debugger Extension for DRED
Debugger Extension for DRED
Microsoft recently announced the release of DRED (Device Removed Extended Data) for D3D12 in the Windows 10 May 2019 Update (previously referred to as the Windows 10 19H1 Preview).  Buried in that post is a mention that Microsoft is working on a debugger extension to help simplify post-mortem analysis of DRED.  Good news, that debugger exten
OS Variable Refresh Rate
OS Variable Refresh Rate
[Updated June 13th to clarify support for FreeSync] With Windows Version 1903, we have added a new toggle in Graphics Settings for variable refresh rate. Variable refresh rate (VRR) is similar to NVIDIA’s G-SYNC, AMD's FreeSync, and VESA DisplayPort Adaptive-Sync. This new OS support is only to augment these experiences and does not re

DirectX 12 boosts performance of HITMAN 2
Our partners at IO Interactive, the developers of the award-winning HITMAN franchise, recently added DirectX 12 support to HITMAN 2, with impressive results.  IO Interactive was so excited that they wanted to share a bit about how their innovative use of DirectX 12 benefits HITMAN gamers everywhere. The guest post below is from IO Interact

New in D3D12 – background shader optimizations
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
