# D3d12info

A Windows console program that outputs 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.

![Example output](https://raw.githubusercontent.com/sawickiap/D3d12info/master/Docs/Gfx/Example_output.png "Example output")

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`.

# GUI and online database

- 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](https://github.com/Devaniti))*

# Download

To download compiled binary of this console app, go to **[Releases](https://github.com/sawickiap/D3d12info/releases)**. This is a portable program - it doesn't need installation.

Version history can be found in file [CHANGELOG.md](CHANGELOG.md).

# Features

Following types of information are printed by the program:

- List of available DXGI adapters (GPUs) available in the system and their parameters, e.g. video memory size.
  - Software and WARP adapters can also be used (off by default).
- Direct3D 12 capabilities of the GPU, like `D3D12_FEATURE_DATA_D3D12_OPTIONS`, `D3D12_FEATURE_DATA_D3D12_OPTIONS2`, etc.
  - Latest DirectX Agility SDK is used for access to the latest features.
  - Preview version of the Agility SDK is supported by a separate executable "D3d12info_preview.exe".
- Capabilities of all the formats (off by default), e.g. whether `DXGI_FORMAT_R9G9B9E5_SHAREDEXP` can be used as a render target.
- Available meta commands and their parameters (off by default).
- Graphics driver version, fetched in a multitude of ways.
- Basic information about the operating system, e.g. Windows version, system memory size.
- Basic information fetched from Vulkan, focused on general GPU description and driver version.
- On AMD GPUs: Information fetched using their AGS library and device_info library, e.g. more detailed parameters of the hardware and the availability of custom extensions like `userMarkers`, `appRegistration`, `shaderClock`.
- On Nvidia GPUs: Information fetched using their NVAPI library, e.g. more detailed parameters of the hardware and the availability of custom extensions like `NVAPI_D3D12_RAYTRACING_CAPS_TYPE_THREAD_REORDERING`, `*OPACITY_MICROMAP`, `*DISPLACEMENT_MICROMAP`.
- On Intel GPUs: Information fetched from their GPU Detect library, e.g. more detailed parameters of the hardware.

Output is printed in a human-readable text format by default, but it can be switched to **JSON** format suitable for automated processing.

Following types of information are **not supported** by the program:

- Listing outputs (monitors) connected to the GPU or their parameters.
- DirectX Video.
- More information fetched from Vulkan, like extensions, properties, or limits. For them, please use [Vulkan Hadware Database by Sascha Willems](https://vulkan.gpuinfo.org/) and its accompanying app.
- Information fetched from Windows Display Driver Model (WDDM) API.

# Command-line syntax

  --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.
