 ## SteamVR Release Notes and Known Issues
 
-**This is a development release**. It is intended to allow developers to start creating SteamVR content for Linux platforms. Limited hardware support is provided, and pre-release drivers are required. **Linux support is currently only available in the "beta" branch**, make sure you are using SteamVR[beta] before reporting issues.
-
-**SteamVR on Linux is only supported on the latest version of the Steam Beta Client**. Make sure you are opted into the public Beta of the Steam client or SteamVR will not run due to missing dependencies.
+**This is a development release**. It is intended to allow developers to start creating SteamVR content for Linux platforms. Limited hardware support is provided.
 
 **SteamVR and VR apps require a special build of the 64-bit Vulkan loader, which is included in the Steam Runtime**. Make sure a system copy of libvulkan isn't being picked up by SteamVR or the games, which might involve disabling STEAM_RUNTIME_PREFER_HOST_LIBRARIES if you have a libvulkan installed on your system.

 SteamVR is built on top of the Vulkan API and requires the latest Vulkan drivers. 
 
-**NVIDIA cards require version 375.27.xx of the NVIDIA Developer Beta Driver**. This can be downloaded from https://developer.nvidia.com/vulkan-driver. A Debian packaged version of this driver can be found in the "NVIDIA Development Drivers" PPA at https://launchpad.net/~mamarley/+archive/ubuntu/nvidia-dev/+packages. If you're also  using the graphics-drivers PPA, make sure the nvidia-dev PPA is pinned higher to use its driver over the nvidia-375 package in the graphics-drivers PPA. Thanks to Michael Marley for maintaining this PPA! Add the PPA with the following:

-AUR packages providing the NVIDIA Developer Beta Driver are available for Arch Linux thanks to [gehneo on the SteamVR for Linux forum](http://steamcommunity.com/app/250820/discussions/5/133257959063392200/). Install with the following:

 The NVIDIA driver supports direct mode, meaning the HMD will not appear on your desktop, or if it does, the display will have to be turned off in xrandr before being able to use VR.
 
-The latest driver in NVIDIA's stable branch has a higher version number, but will not work. You need the driver from the vulkan development branch that is at almost exactly version 375.27.xx.
-
 **AMD graphics require a specific tree of the radv driver**. Use the **radv-wip-steamvr** branch of this repository: https://github.com/airlied/mesa. It doesn't support direct mode currently, so the HMD display will have to be positioned on your desktop in extended mode, and your system compositor disabled while using VR.
  
 **Intel graphics are not currently supported**.

 ## UNITY DEVELOPMENT
 
-**Linux OpenVR development requires version 5.6 of Unity**. This can be downloaded from https://unity3d.com/unity/beta. Only the Vulkan renderer is currently supported on Linux. To select the Vulkan renderer, go to Edit->Project Settings->Player. Uncheck "Auto Graphics API for Linux" and add "Vulkan (Experimental)" to the Graphics APIs for Linux option.
-
-If you are using the Unity SteamVR plugin, **download the latest plugin from the Unity Asset Store** at https://www.assetstore.unity3d.com/en/#!/content/32647. Older versions of the plugin do not support Linux.
-
-There is a known issue with the Lab Renderer adaptive quality and Unity 5.6. If your project is using the SteamVR Lab Renderer, disable adaptive quality. (select your camera, and uncheck "Adaptive Quality Enabled" on the Valve Camera script pane)
+Unity development is not currently supported.
 
 ## KNOWN ISSUES
 * OpenGL applications are currently too slow to use interactively; only the Vulkan Submit path is optimal. See: https://github.com/ValveSoftware/openvr/wiki/Vulkan
