Resonite #

Note: The Linux-native version of Resonite, amid deprioritization of developer time to fix its numerous issues, was put on indefinite hold in August 2024 and later removed in March 2025. This document only covers running under Proton.

The current recommended Proton variant is GE-Proton-RTSP.

OpenComposite should now provide a close-to-flawless experience on most controllers and when using hand tracking.

Visual bugs #

There are some minor visual bugs specific to running Resonite on Proton, such as textures taking longer to load and appearing black for a few seconds when close to the player.

Mirrors look cross-eyed #

When playing Resonite under Monado or WiVRn, the 3D effect of mirrors may appear way off, as if looking through them feels like your eyes are crossed. This only affects headsets with canted displays (e.g. Valve Index, Pimax).

To solve this, prepend OXR_PARALLEL_VIEWS=1 to Resonite’s launch options.

Crashes #

Resonite has been seen causing random SteamVR crashes on Linux before. In some situations the engine also tends to freeze. On OpenComposite, the game will rarely close out on its own without leaving any obvious trace of things going wrong — this is being investigated.

The cause of these issues and whether they are Proton-specific isn’t currently known.

Performance #

In larger sessions Resonite is typically CPU-bound, there isn’t much that can be done besides upgrading your CPU. In situations where the GPU is a bottleneck, lowering the resolution (either in the OpenXR runtime or through OpenComposite) may help dramatically. This can be easily done by prepending OXR_VIEWPORT_SCALE_PERCENTAGE=75 to Resonite’s launch options. Experiment with different values to find your preferred balance between performance and quality.

Crash on loading into a world with video players #

On GE-Proton9-10 (for example), loading into a world with e.g. a YouTube video or live stream can crash the game. Try using the latest GE-Proton-RTSP release.

Controls busted after switching to desktop #

Resonite allows a VR player to take a break and switch to desktop mode by pressing the F8 key.

Because controller hot-swapping is not yet implemented in Monado & OpenComposite, turning off a controller will freeze its state, including buttons pressed and analog stick input. Resonite will continue processing VR inputs even after switching to desktop.

The end result is that desktop controls can act strangely. For example, if you were holding the grab sensor as you turned off the VR controller, picking up items or inspector windows stops working with the mouse.
