Deep Live Cam Studio 2.2.0 Windows Release

This release adds a verified DirectML build for AMD and Intel GPUs and fixes a
file Preview/Render deadlock that could also affect CUDA systems.

Use the CUDA installer for NVIDIA GPUs. Use the DirectML ZIP for AMD or Intel
DirectX 12 GPUs: extract it into a new folder and run
DeepLiveCamStudio.exe. Do not copy one runtime over another.

What Changed

Added

  • DirectML GPU acceleration for AMD and Intel GPUs, including strict provider
    verification and multi-GPU adapter selection.
  • A versioned DirectML portable ZIP with a SHA-256 sidecar and release-time
    archive validation.

Fixed

  • Preview and Start Render can no longer re-enter while the first file
    operation is loading models, preventing the observed Not Responding
    deadlock.
  • DirectML face analysis uses the CPU compatibility path while swap and
    enhancement inference remain on the GPU, avoiding Radeon multi-session
    hangs.
  • GitHub packaging now preserves dot-prefixed runtime directories, including
    the scikit-learn .libs DLL required by the application.
  • Clean NVIDIA installer builds now include the pinned CUDA 12/cuDNN 9 runtime
    DLL set required for an actual ONNX Runtime CUDA session.
  • Provider diagnostics fail clearly when requested GPU acceleration is not
    active instead of silently treating CPU fallback as success.

The final DirectML artifact was validated by the issue reporter on a Radeon
6900 XT for file rendering and Live Output. CUDA rendering and Live Output were
also verified locally on an NVIDIA RTX 4070.

Source and license

Deep-Live-Cam is licensed under AGPL-3.0. Complete corresponding source for the
exact binary release is attached and identified by the source ref above.

The source archive is produced with:

powershell -ExecutionPolicy Bypass -File build\windows\package_source.ps1 -AppVersion 2.2.0 -GitRef 0e2617e0c944f911aa26c144878292e0272270c9

This release preserves attribution to the original project:

Models are not bundled

The installer intentionally does not include model/checkpoint files. The
DirectML portable ZIP also excludes them because model licenses and
redistribution rights are separate from the application license.

After launching, select Set Up Models, or run:

DeepLiveCamStudioCLI.exe --download-models

Downloaded models are stored under:

%LOCALAPPDATA%\DeepLiveCamStudio\models

Requirements and known limitations

  • ffmpeg and ffprobe must be installed separately for video workflows.
  • OBS Studio must be installed separately for OBS Virtual Camera workflows.
  • The public files are unsigned and may trigger Microsoft Defender
    SmartScreen.
  • Face-swap and enhancer model families retain their documented
    non-commercial or research-use restrictions; no model weights are
    redistributed here.

Release evidence

This release candidate is not publish-approved by release notes alone;
publish approval is recorded in RELEASE_VERIFICATION.md,
MANUAL_RELEASE_GATES.md, and the signed gate documents included with the
upload.

Completed local evidence is included in the uploaded release documents:

  • Full automated test suite.
  • Packaged CUDA and DirectML runtime/provider checks.
  • Installer smoke install/uninstall checks.
  • Model download/checksum and forbidden-model scans.
  • CUDA and DirectML file-render checks.
  • Radeon 6900 XT and NVIDIA RTX 4070 Live Output checks.

Remaining publish blockers:

  • None when RELEASE_VERIFICATION.md says Ready to publish without remaining manual gates: YES.

Completed manual signoffs include:

  • Clean Windows install without admin rights.
  • OBS Virtual Camera and DirectML Live Output workflows.
  • Authorized legal review for dependency, model-license, and redistribution obligations.
