SteamFrame Advanced Options is the new name of the app and repository. This release adds two bundled HEVC presets and more encoder controls, and includes all v1.4.1 streaming reliability fixes.

Bundled presets

Preset Bitrate target Encoding
Smooth HEVC 300 Mbps Single-pass VBR, original gaze quality
High quality HEVC 400 Mbps CBR without padding, quarter-resolution multipass, gaze/periphery offsets of −2/−6
Full-resolution HEVC — Experimental 400 Mbps High quality HEVC with full-resolution multipass analysis

All three use 90 Hz, 10-bit HEVC and a 2048-pixel stream width. Select a preset in Stream settings, review its controls, then Apply. Built-ins remain available alongside personal presets.

Bitrate values are targets, not guaranteed throughput. Full-resolution multipass has not been shown to improve headset quality or bitrate and can worsen frame timing. High quality HEVC retains the previously measured settings.

More encoder options

  • Full-resolution multipass joins Valve default, single pass and quarter-resolution multipass.
  • Optional GOP bitrate consistency and keyframe I/P bit ratio controls can be saved in personal presets, with requested, pending and accepted readbacks.
  • These two advanced controls require a new encoder session and remain unset in the built-in presets. Keyframe ratio is intended for CBR with single-frame VBV.

Download and upgrade

Download SteamFrame-Advanced-Options-win-x64.zip, extract the entire folder, and run SteamLinkVRSettings.exe. The portable package includes the .NET and Windows App SDK runtimes. The executable and settings storage keep their existing names so personal settings and presets remain compatible.

Close the old app before switching copies. The app display name, repository and ZIP now use SteamFrame Advanced Options. SHA256SUMS.txt contains the archive checksum.

Validation

  • Release build passed, with 74 managed tests, six native encoder test suites, 25 compositor timing assertions and 21 codec companion tests passing.
  • Native helper export and read-only checks passed. The absent-server Start check was skipped because SteamVR was running.
  • The driver patch fixture test was skipped because no fixture was configured.
  • Portable archive integrity, UI resource presence, version/name metadata and bundled codec runtime provenance were checked. The codec runtime is unchanged from v1.4.1.
  • No new headset gameplay benchmark was performed for this release.
