Welcome to the VRCX wiki!

Here you'll find feature documentation, developer resources, and general information such as info below.

Transfer VRCX data to a new PC

• All VRCX data is stored in a SQLite database inside your %AppData%\VRCX folder VRCX.sqlite3, VRCX.sqlite3-shm, VRCX.sqlite3-wal and VRCX.json contains a few extra settings.
• TL;DR: Copy %AppData%\VRCX (C:\Users\user\AppData\Roaming\VRCX) folder from your old PC to the same location on your new PC.

Common issues

VRCX wont open or opens to a white screen

This can be caused by a many different things here's a list of things to try:

• VRCX memory leak, hopefully this wont be an issue for long.
• Install Microsoft Visual C++ Redistributable 2019.
• Reboot your computer, maybe another process is trying to read the database file.
• Disable antivirus software, Avast and AVG are known to delete Cef/VRCX.
• Remove AVerMedia AssistCentral this is known to cause problems with VRCX for some unknown reason.
• Unstable RAM can be a potential cause, remove any RAM overclock and run MemTest86.
• Test a fresh database, first close VRCX then backup your current database by opening %AppData% and renaming the VRCX folder to something like VRCX.Backup, if this solves it but you'd like to still keep your data follow the steps bellow on how to repair your database.

The SSL connection could not be established

• Disable any VPN, if this fixes the issue, you may be able to add an exception for VRCX to continue using the VPN.
• Change DNS server to something like Cloudflare.
• Try Cloudflare warp.
• If you have multiple uplinks or your IP changes often you may need to use a VPN.
• Manually update root certs, run PowerShell as admin and paste this in.

mkdir C:\trusted-root-certs
cd C:\trusted-root-certs
Certutil -generateSSTFromWU roots.sst
$sstStore = (Get-ChildItem -Path c:\trusted-root-certs\roots.sst)
$sstStore | Import-Certificate -CertStoreLocation Cert:\LocalMachine\Root

VRCX running slow

• Settings > Appearance > Max Table Size
  • Lower this value to something like 100 this will decrease the amount of table entries stored in RAM.
• Settings > Advanced > Auto Clear Cache
  • Lower this interval to something like 3 hours this will decrease the amount of unnecessary worlds, users and avatars stored in RAM.

SteamVR Overlay not working

• Disable SteamVR safe mode.
• Ensure SteamVR isn't set to a legacy version in Steam -> Properties... -> Betas.
• If your computer has an iGPU follow these steps.
