You can download the latest Appimage snapshot from [GitLab Pipelines](https://gitlab.com/gabmus/envision/-/pipelines).
**Please note that WiVRn will not work properly by AppImage, if you utilize the AppImages to run WiVRn you must extract the contents of the AppImage and then execute the Envision binary.**
## Room Setup
If you're planning to use the SteamVR lighthouse driver (with Index or Vive HMDs, or other lighthouse tracked HMDs), you'll need to go through the SteamVR room setup. You can do that from SteamVR, directly from Envision or manually by running the appropriate scripts. More info in the [SteamVR page](/docs/steamvr).

### Full body lighthouse tracking
These patches enable fairly hacky full body support for steamvr_lh and survive drivers in monado. Both of these must be used in conjuction or your XR application will crash or hang.
For the Envision xr service settings:
Repo `https://gitlab.freedesktop.org/BabbleBones/monado/`
Branch `vive_tracker3`
For the Envision OpenComposite settings:
Repo `https://gitlab.com/BabbleBones/OpenOVR`
Branch `htcx-fbt`
Full body is now provided by default in Monado & OpenComposite through the XR_MNDX_xdev_space OpenXR vendor extension. This allows any tracked "xdev" in Monado to be forwarded as a raw pose without bindings to applications. OpenComposite exposes these as fake vive FBT trackers for use.

> Monado is an open source XR runtime delivering immersive experiences such as VR and AR on mobile, PC/desktop, and other devices. Monado aims to be a complete and conformant implementation of the OpenXR API made by Khronos. The project is currently being developed for GNU/Linux and aims to support other operating systems such as Windows in the near future.
Essentially, Monado is an open source OpenXR implementation, it can be used as an alternative to SteamVR.

To use Monado as the OpenXR runtime with Steam, or if you're planning to use the SteamVR lighthouse driver in Monado, make sure to [run the room setup first](/docs/steamvr/).
In order to use the SteamVR lighthouse driver in Monado, you just need to set the environment variable `STEAMVR_LH_ENABLE=true`.
OpenComposite is REQUIRED to operate Monado in conjunction with Steam games. Proton requires a functional OpenVR API to utilize OpenXR at all and Proton itself is required for VR to function as normal wine does not carry any of the needed patches nor does "protonified" wine something like Lutris would provide.
## Envision
[Envision](/docs/envision/) provides fairly low barrier setup and development of both Monado and OpenComposite on most any modern distro.

Please note the OpenVR implementation is incomplete and contains only what's necessary to run most games for compatibility. If you plan to implement software, utilize the OpenXR API, specification [here](https://registry.khronos.org/OpenXR/specs/1.0/html/xrspec.html).
OpenComposite is required for Steam Play games to work in VR regardless of API. Due to the number of confounding factors surrounding setup, sandboxing, and more quirks; we recommend you use Envision to setup and manage your VR.
Contributions to improve the OpenVR to OpenXR mapping are welcome.

# Performance
## A word on antialiasing
Antialiasing should be avoided when possible and the compositor scale should be increased in monado to smooth out edges. In general AA is found to increase the latency of delivered frames quite noticably and the GPU utilization far more than simple super sample of the actual VR session or app.
## Set AMD GPU power profile mode
This is important to avoid stuttering.
AMD GPUs will attempt to power save in between rendering frames, for flatscreen games this is helpful, but for VR this is quite negatively impactful on the VR compositor's ability to timewarp frames so the user's viewport does not stutter or cause sickness.
This is very important to avoid stuttering, do not skip this step if you use AMD.
### The simple way: Use CoreCtrl

# Did all of this and still suffering stuttering issues, discomfort, or sickness?
You may need to increase the overhead of your compositor timewarp. Some GPUs cannot effectively meet the demands of realtime reprojection on the default value of 4 miliseconds so a safer value of 8 can be recommended if your symptoms are accompanied by 100% GPU usage:
`U_PACING_COMP_MIN_TIME_MS=8`
Insert this enviornment variable into your monado-service launch or into your envision profile and simply start the runtime without a rebuild. Bump the value up, as appropriate, based on the absolute power of your GPU.
Lower spec users such as iGPUs and more should consider radically higher values here, experiment in the double digits to arrive at a number that works well from your perspective.

# Resonite
## Broken Textures
Resonite presents a decent base of usability for both native linux and proton verions but suffers some issues under OpenComposite.
If the floor or menu appear invisible/corrupted, try installing the [TextureFix](https://github.com/rcelyte/ResoniteTextureFix/releases/latest) mod.
## Broken hands
Resonite is currently playable on Valve Index controllers alone through OpenComposite. The SteamVR runtime normally generates synthetic hand models from the user's controller activity but OpenComposite does not currently support this leading to null hands passed in.
Valve Index Knuckles generate their own synthetic hand data in the Monado runtime and therefore function as expected.
