v20.3.0 Changelog

Caveats

• Hand tracking to touch inputs have been removed. In the next release we are adding them back together with a whole new configurable hand tracking gesture system.
• Controller tracking is broken on Pico PUI v5.8. This applies to all previous releases too. We are investigating the issue. You are encouraged not to update.

ALVR v20.3.0

ALVR v19.0.0

Changes

• Fix UDP stutter and image corruption in most circumstances (by @zarik5)
  • This is fixed by increasing the receive/send buffer size of the socket. Advanced options available in the Connection tab.
  • Huge thanks to @xytovl for the idea!
• Reduce image jitter (by @zarik5)
  • Increase maxBufferingFrames (Settings -> Video -> Enable advanced options) to reduce jitter caused by network and transcoding, at the expense of more latency. It cannot mitigate frame drops on the server side.
• New more accurate latency and FPS statistics (by @zarik5 #1061)
• New AppImage packages on Linux (by @m00nwtchr #1181)
• Better audio support on Linux (by @makomk #1065 #1066, @zarik5, @m00nwtchr #1068)
  • Audio on Linux is still hard to make it work. There is ongoing work to change this
• Add Oculus foveation options (by @zarik5 #1079)
• New advanced controller tracking options (by @zarik5 #1103)
• Improve controller support (by @Solexid #1076 #1078)
• Add 10 bit encoding support on AMD (by @deiteris #1223)
• New advanced encoder settings for Nvenc and AMF (by @zarik5, @deiteris #1220)
• Add “Force Software Encoding” option (by @Vixea /formerly @ColdIce1605 #1073)
• Reorder encoder initialization tests (NVENC->VAAPI->SW) (by @m00nwtchr #1032)
• Improvements to adaptive bitrate (by @sctanf, @grypr #1141)
• Do not disconnect client when an audio device is unplugged (by @algologarithm #1124)

• Set TCP_NODELAY (by @korejan)

Thanks also to @daggintosh, @ImUrX, @toomuchcodehelp, @HookedBehemoth, for some other smaller changes.

Caveats

• Some users report issues with controller tracking. If you feel tracking does not feel right you can tweak a few parameters to get the exact feel you need. Go to Settings -> Enable Advanced Options -> Headset, the parameters to tweak are clientControllerPredictionMutlitplier, trackingLatencyOffsetMs, steamvrHmdPredictionMultiplier, steamvrCtrlPredictionMultiplier. Changing these values requires a headset sleep/wake cycle (press the power button two times) but not a restart of the server.

Headsets support

• The Meta Quest Pro is supported without any particular changes on our side. Eye/Face/Body tracking is currently unsupported; support is planned.
• The Oculus Go support is dropped. Due to internal changes, ALVR now only supports Android >= 8.
• New GearVR and Google Cardboard ALVR clients are almost ready. We need your help with bug fixing and testing. Nightly builds are provided.
• The nightly builds include a alvr_client_core SDK to create new ALVR clients! If you are a developer and you are interested in helping support new headsets tell us in the ALVR Discord Server.

ALVR v18.2.3

• Fix missing x264/5 shared libraries for xtask --bundle-ffmpeg/portable builds (by @korejan)
