My next little hobby project is D3d12info. It is a Windows console program that prints all the information it can get about the current GPU installed in the system, as seen through Direct3D 12 API. It also fetches additional information through AMD GPU Services (on AMD cards), NVAPI (on NVIDIA cards), Vulkan, and WinAPI, mostly to identify the current version of the graphics driver and Windows system. I will try to keep it updated to the latest Agility SDK, to query it for support for the latest hardware features of the graphics card.
The tool can be compared to DirectX Caps Viewer you can find in your Windows SDK installation under path "c:\Program Files (x86)\Windows Kits\10\bin\*\x64\dxcapsviewer.exe" in terms of the information extracted from DX12. However, instead of GUI, it provides a command-line interface, which makes it similar to the "vulkaninfo" tool. Information is printed in a human-readable text format by default, but JSON format can be selected by providing
-j parameter, making it suitable for automated processing. Additional command-line parameters are supported, including a choice of the GPU if there are many installed in the system. Launch it with parameter
-h to see the command-line syntax.
In the future, I would like to extend it with a web back-end that would gather a database of various GPUs and driver versions, like Vulkan Hardware Database does for Vulkan, and to make it browsable online. As far as I know, there is no such database for D3D12 at the moment. Best we have right now are the tables about Direct3D Feature Levels on Wikipedia. But that will require a lot of learning from me, as I am not a good web developer, so I will think about it after my vacation :)
