ALVR v15.2.0

• Add 120Hz support
  • 120Hz is only supported for at most 75% resolution, after that you get white artifacts and stuttering.
  • The limits for the refresh rate have been removed for the advanced setting, but the server and client will always run with one of the supported values.
• Frame timing optimization on client
  • This should reduce white artifacts.
• Make 10 bit encoder option a basic setting
• Make encoder error more descriptive

Known bug: the firmware v28 for Oculus Quest 1 and 2 introduces a bug that breaks microphone recording when using wireless headphones.

ALVR v15.1.2

• Fix dashboard window appearing out of the screen bounds
• Fix autodetection of VoiceMeeter audio devices

ALVR v15.1.1

• Add option to disable client discovery
  This makes connecting the client through USB easier.
• Add official support for Voice Meeter as an alternative for VB-CABLE (for microphone streaming)
• (Probably) fixed bug where the dashboard would sometimes not load and remain blank.

ALVR v15.1.0

• Better support for USB connections (by @Drakulix)
  • A guide for using ALVR with USB tethering will be written soon.
• Include the correct DLL for C++ runtime (by @maxer456)
  • Now ALVR should never need the Visual C++ redistributable anymore.
• Add advanced setting for 10 bit video encoding (by @maz-d-9)
  • This setting reduces color banding.
  • Has effect only for Nvidia graphics cards.
• Various encoder optimizations on AMD graphics cards (by @Armarr)
• Deny use of audio devices with more than 2 channels (by @zarik5)
• Client optimizations (by @Drakulix and @zarik5)
• Allow advanced audio device setting to accept microphones as recording devices (by @zarik5)
• Korean translation update (by @wonjj0317)
• Various UI fixes (by @zarik5, @Armarr, @sctanf, @Ekristoffe)

ALVR v15.0.0

This release rewrites the sockets implementation used for streaming. You can save 5 to 10ms of latency.
In the Connection tab you can choose between UDP, Throttled UDP and TCP socket protocols:

• UDP has the lowest latency but works best at very low bitrates (<30 Mbps). Higher bitrates cause packet loss and stutter.
• Throttled UDP is an experimental reimplementation of the previous socket. It works best at medium bitrates (~100 Mbps). At low bitrates it could have excessive delay and at higher bitrates is has the same problems as UDP.
• TCP works well up at any bitrate up to 250 Mbps. It has the highest latency (but still lower than the previous ALVR versions). This is the new default.

If you didn't, check the release notes for ALVR v14.2.0.

In this release:

• New sockets implementation (by @zarik5 and @maxer456)
• Audio crackling fix (by @zarik5)
  • Crackling is fixed but you may still experience stutter, especially on TCP. In this case increase the Buffering setting value, at the cost of more latency.
• Automatic SteamVR audio configuration (by @zarik5)
  • This works only if input and output audio device is set to "Headset" in SteamVR settings
• Fix Guardian sync misalignment (by @maxer456)
• Fix video stream not starting sometimes (by @maxer456)
• Add German translation for settings (by @Noel-Sa).
• Add Korean translation (by @wonjj0317).
• Add "The Walking Dead: Saint & Sinners" preset in the presets folder.

The autoupdater cannot be used to upgrade to this version. You need to download and install the update manually.

ALVR v15.0.0-beta.2

Stability improvements

ALVR v15.0.0-beta.1

Fix audio crackling. Fix guardian sync.

ALVR v14.1.1

• Signed Quest and Go apps with a release certificate.
• Disabled autoupdater to avoid incompatibilities with the next release

ALVR v14.2.1

Add option to specify audio device by name.

ALVR v14.2.0: Reduced sound and microphone latency

This release rewrites the audio streaming code to achieve lower latency and better compatibility with sound devices.

• New system for streaming sound and microphone (@zarik5):
  • It uses cross-platform libraries and it's ready for Linux support (you can test audio streaming on Linux now! https://github.com/alvr-org/ALVR/wiki/Build-from-source#linux-experimental-build).
  • Fixed bug with latency runaway.
  • You can choose between less latency or less crackling with the setting "Latency offset".
  • As with previous releases, you need to install VB-CABLE to use the microphone. https://github.com/alvr-org/ALVR/wiki/Installation#microphone-streaming
• Rewritten launcher (by @zarik5):
  • Fixed glitched state when there is no internet or slow connection.
  • The button "Reset drivers and restart" now can recover from an old ALVR installation with a path with non UTF-8 characters.
• New autoupdater (by @Ekristoffe and @zarik5):
  • It can show the changelog and the download progress.
  • It now updates ALVR using the installer. When prompted you need to give administrator permissions.
• Removed need for Visual C++ Redistributable:
  • The DLLs are bundled with the ALVR release
  • We couldn't test this properly. If you have any problem, install the latest x64 redistributable here: https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0
• Add settings for executing commands on connection and disconnection (by @DavisNT).
• Better network interruption detection using keep-alive packets (by @DavisNT).
• Add Dutch translation (by gman and @Armarr).
• Add Slovenian translation (by @CathodeXT).
• General UI improvements (by @Ekristoffe).

Compatibility note: this release works with server or client on other v14.X.X releases, but the audio streaming will not work.
This release broke the previous autoupdater. Please uninstall the previous version and install this version manually.
