A Windows console program that gets all the information about the GPU (graphics chip) installed in the system, through DXGI and Direct3D 12 (D3D12) + AMD AGS, NVAPI, WinAPI, and some other sources.

Inspired by vulkaninfo - a similar tool that prints all the information about device capabilities using Vulkan API.

An alternative for D3D12 is a GUI program "DirectX Caps Viewer", which is part of Windows SDK and can be found in path like: c:\Program Files (x86)\Windows Kits\10\bin\*\x64\dxcapsviewer.exe.

• Online database of GPU capabilities:
  • https://d3d12infodb.boolka.dev/
• GUI application that can display the capabilities of the current GPU and submit them to the database:
  • https://github.com/Devaniti/D3d12infoGUI/releases

(These projects are managed by @Devaniti)

To download an archive with compiled binary of this console app, go to Releases. This is a portable program - it doesn't need installation.

Version history can be found in file CHANGELOG.md.

Options:
  -v --Version                     Only print program version information.
  -h --Help                        Only print this help (command line syntax).
  -l --List                        Only print the list of all adapters.
  -a --Adapter=<Index>             Print details of adapter at specified index.
  --AllNonSoftware                 Print details of all (except WARP and Software) adapters (default behavior).
  --AllAdapters                    Print details of all (except WARP) adapters.
  -j --JSON                        Print output in JSON format instead of human-friendly text.
  -f --Formats                     Include information about DXGI format capabilities.
  -e --Enums                       Include information about all known enums and their values.
  --PureD3D12                      Extract information only from D3D12 and no other sources.
  -x --EnableExperimental=<on/off> Whether to enable experimental features before querying device capabilities. Default is off for D3d12info and on for D3d12info_preview.
  --ForceVendorAPI                 Tries to query info via vendor-specific APIs, even in case when vendor doesn't match.
  --WARP                           Use WARP adapter.
