When the Rift S launched, haptic feedback on the Touch controllers wasn’t working in SteamVR. Valve released a hotfix less than 24 hours later to resolve this.
Over the last few weeks, Valve has been expanding support for Facebook’s new headset in SteamVR Beta builds. SteamVR now visually shows the new Touch controllers in the Dashboard, Home, and apps which use the default SteamVR controller model.
Before this release, SteamVR (non-Beta) detected the Rift S as a regular Rift with three sensors. This is how the Oculus runtime presents the VR hardware to apps built on older SDKs. Now that Valve is using the latest Oculus SDK, Rift S is detected as its own headset, with its own (higher) default resolution and no external sensors.
The Steam store has also been updated to consider Rift S compatible with all games marked as compatible with Rift. Beforehand Rift S users would see a message warning them that their headset was incompatible.
With the Rift S, users can redraw their Guardian boundary from inside VR using the black & white Passthrough+ mode. SteamVR now detects when this happens so as to position VR content in the center of the space without the need for restart.
The release is also supposed to fix “numerous stability issues and bugs”.
