Troubleshooting Update 29

How to address issues with the new update.

Pavlov has had a significant engine upgrade which required us to switch to the new OpenXR API. This requires the end-user's attention to often enable OpenXR for their runtime software. Additionally, some runtime software is not live with OpenXR fixes but may have a Beta branch available to fix your issue.

Please get in touch with our support team at [e-mail] if the contents of this guide do not address your issue. Please provide your headset details, the software you use with your VR headset, and the troubleshooting steps you have already performed.

General Game launch issues

Black screen in headset, game will display on monitor, some headsets don’t launch at all.

Make sure OpenXR is set for your runtime, Please refer to your headset section in this guide on how to accomplish this. Additionally, consider installing OpenXR Toolkit[mbucchia.github.io] to resolve any launch or performance issues.

Mods

I want to clear my mod content folder

App data is where mod.io content goes by default.
“C:\Users\YOURUSERNAME\AppData\Local\Pavlov\Saved\Mods” is where files usually go.
You would delete this to completely clear out unwanted, corrupted, or bad mod files.

I cannot download mods.

If your computer name is using non-english alphabet characters such as cyrillic, kanji, hangul, etc you may have to set a custom folder somewhere on your hard drive that does not use those characters. Please refer to the section below.

I don’t want to store maps from Mod.io on my windows drive or localappdata

Look for “ModDirectory=” line in GameUserSettings.ini to change your mod directory.
Move the contents of the default mods folder to your new specified directory. If you have no mods downloaded yet, be sure to create the folder before adding to your GameUserSettings.ini

GameUserSettings.ini can be located at
AppData\Local\Pavlov\Saved\Config\Windows\GameUserSettings.ini on your windows installation.
To access your local app data, in the windows search bar type %localappdata% and press enter.

Microphone and In-Game issues

I cannot change my mic device in game

To fix the microphone device issue, delete the text after "VoiceDevice=" from:
%localappdata%\Pavlov\Saved\Config\Windows\GameUserSettings.ini, and then set what mic you want to use as the windows default.

If you are on Quest 2 use "Headset Microphone (Oculus Virtual Audio Device)"

I am seeing random black lines on the screen.

There have been some AMD graphics cards that have been presenting visual artifacts in the game for some players. Unfortunately this is something on the GPU driver level that we cannot currently address at this time. There has been some success on downgrading the drivers to 20.10.1 with a full driver uninstall with DDU, but it has not worked for everyone:
