Launch Options
Advanced Options
These options are more advanced and designed to help creators debug issues with their creations.
There are several launch options available for VRChat.
If you are using Steam, you can set these easily in the Properties for VRChat, found by right-clicking on VRChat's entry in your game list. After clicking Properties, click on Set Launch Options, then put your desired launch options in.
If you are using Oculus PC, you must create a shortcut to the VRChat executable. After launching Oculus Home, launch this shortcut by clicking its icon. The Oculus launcher does not support launch options natively.
Oculus Quest does not support any of these launch options.

If all your trackers have disconnected so the calibration option is no longer visible, cycling the Avatar Measurement option will also unfreeze them |
Resolution and Screen Choice
Unity 2019 removed the ability to launch a dialog by holding shift/alt when launching, but you can use launch arguments to replace much of that functionality.
Launch Option | Description |
|---|---|
-screen-width | Override the default screen width. This must be an integer from a supported resolution. |
-screen-height | Override the default screen height. This must be an integer from a supported resolution. |
-screen-fullscreen | Override the default full-screen state. This must be 0 or 1. |
-screen-quality | DOES NOT WORK - just listing it because you might try it and get confused. |
-monitor N | Run Standalone Player on the specified monitor, indicated by a 1-based index number. |
You can find them here, under the "Unity Standalone Player command line arguments" section.
Note that most (if not all) of the force launch options will cause issues that prevent you from using VRChat.
Ensure that you select the correct version of Unity using the selector in the top left. Refer to the Currently Supported Unity Version page to see what version VRChat is currently using.
