Firestorm 188.8.131.52799 with OpenSimulator viewer is a Beta test viewer which includes support for EEP (the Environmental Enhancement Project) and support for the Chrome Embedded Framework Live Video Streaming features in Second Life and OpenSim. VR Mode in this new version acts in the same way as in Firestorm VR Mod 6.3.9. See
Peter Kappler maintains the Firestorm VR Mod Viewer and his source code modifications to allow the Firestorm Viewer to work with VR headsets at https://gsgrid.de/firestorm-vr-mod/ – go there to download his latest version and for usage information, source, advice on trouble shooting, etc. For community support use the Discord Discussion Channel: P373R-WORKSHOP by p373r_kappler [ Invite ].
On that channel @humbletim has announced an automated scripted build system with help from @thoys using GitHub Actions (GHA) which merges Peter Kappler’s VR code additions into stock Firestorm and which can autobuild a release executable version. He has done that for Firestorm 184.108.40.206205 and 220.127.116.11799. See https://github.com/humbletim/firestorm-gha/. Look under the Releases tab and the installer is under the “Assets” chevron.
These install in to their own folder and use their own user Settings directory so that the VR Mod viewer can be installed alongside the standard Firestorm viewer. Note that if you want to import existing Firestorm accounts/settings you have to manually copy them over between AppData/Roaming/Firestorm_x64 and AppData/Roaming/FirestormVR_x64 folders.
As usual, Ctrl+TAB initially sets up SteamVR (and HMD support as needed), TAB is used to toggle VR mode on or off, F5 lets you select and step through the various VR HMD or user specific settings for IPD, texture shift to register the left and right eye images, and focal distance to change depth perception, etc. F3/F4 are used to increment and decrement each setting selection.
If you see a lot of hover tips showing under the mouse it could be that the debug setting “ShowHoverTips” is set to TRUE (the default) which may show something constantly under the mouse even for inert unscripted objects. You can turn that off via Debug Settings or via Preferences – User Interface – 3D World – Show Hover Tips.

For anyone wanting to compile from source I was able to get a combined Firestorm stock + VR Mod built using Github Actions (much thanks to @thoys for helping figure it out!).
Still tweaking the build script but latest windows version is here:
And here are the minimum source changes that seem necessary on top of stock Firestorm_6.3.9_Release to merge in the 6.3.3 VR Mod source, fetch OpenVR as a submodule dependency, and then automatically bundle as part of the generated installer.

Ahah… I notice a BIG difference when using 18.104.22.168799 VR Mod… as you tip you head from side to side when in VR Mode the UI elements like the HUDs and name/group tags correctly stay level. BUT the REFLECTIONS of in world items ALSO stay level which looks very odd. In 22.214.171.124205 they correctly stay as a mirror image of the objects. I wonder if the EEP code has altered the graphics layer on which reflections are placed in some way that needs a change to the VR Mod approach? Or if its a bug somewhere in the core Firestorm/Linden Lab rendering code.
Here are screenshots from FS 126.96.36.199205 VR Mod (left) and FS 188.8.131.52799 VR Mod (right) in VR Mode with HMD tipped to the side… click on images for full size versions…
It may be that Linden Lab moved the reflections onto a different graphics layer and the VR Mod code folks might be able to fix that… but it might also partially explain why there is a big frame rate drop in the EEP viewers… as we already know that turning off the UI layer improves frame rate a LOT…. just speculation at the moment but still… interesting.
Looks like its an issue in Linden Lab (and hence Firestorm) EEP code changes.. as it can be observed in the standard non-VR Mod viewers. If you place your avatar so its at an angle (e.g. on a pose stand) and go into Mouselook mode you can see the reflections are wrong… as in the following image…

The issues is in the Linden Lab EEP code and is reported at https://jira.secondlife.com/browse/BUG-229181 and https://jira.firestormviewer.org/browse/FIRE-29972
