Solving Technical Issues

If you're having a technical issue with the game (such as graphical lag, network lag, or other gameplay-disrupting issues) here's what you can do to help us help you.

Graphical Lag

Graphical Lag occurs when you get a "judder" effect in VR. Another way of describing it is that when you move your hand or weapon in-game, it looks like a tuning fork and is vibrating back and forth quickly. If you're consistently seeing this occur:

Make sure your setup is clean

If you have ever installed anything like "OpenVR Advanced Settings", be sure that things like Supersampling are turned off. Also make sure that you have the latest Nvidia/AMD drivers, and that your SteamVR installation is up to date.

Check to make sure the problem is graphical

If you click on the arrow next to the SteamVR title in the window that overlays your game, you can open up the SteamVR Settings window. On this window you will see a "Framerate" counter. Here are two examples of a "laggy" setup and a "good" setup:

If you see a lot of red in your timings, then it's definitely a graphical lag issue. If you don't, then it might be a different issue.

Send us your output log

You can send us your output log (see below under "Reporting Issues" for instructions on doing that) to help us diagnose the problem.

Network Lag

Network lag will manifest itself as things "jumping" around the world, or freezing and then quickly moving all at once. If you're experiencing network lag, consider the following:

Make sure your Internet speed and latency are acceptable

Our servers are hosted in the United States, and you need at least 1mb/s of bandwidth to play OrbusVR. While we do have players from all over the world, it's important that you have a steady connection to the game server. If you're using a non-standard Internet setup like satellite or phone tethering, that could be an issue.

If you open up your output_log file, you will see lines that look like "CURRENT CLIENT LATENCY DIRECT:", make sure that these are consistent and that they are less than 200ms.

Reporting Issues

If you have an issue and need help, please make a post on the Community Forums:

Be sure to include a description of your setup and let us know what steps you've already taken to try and solve the problem. You can also share your output_log with us which will help us diagnose issues.

Your output_log is located under (launcher directory)/resources/app/client/vrclient_Data/output_log.txt

You can upload it to and then share the link with us so we can see it.

Height Drift Issue

You may experience an issue where the height of your setup becomes incorrect over time. This seems to happen over several weeks. If it does, it means that the height that SteamVR thinks your headset is at is mis-matched from the real-world height. To fix it:


1. Open the SteamVR settings menu, by clicking on the arrow next to the SteamVR title in the SteamVR overlay.

2. Go to the "Developer" tab. Then scroll down and find the "Room and Tracking" section. Choose the size of the room from the drop-down that is appropriate for your room size, then place your headset on the floor in the center of your play space, and click on "Quick Calibrate".

3. This should temporarily solve the issue. However, your SteamVR boundaries will no longer be customized for your room -- but your Oculus Guardian boundaries still will show you the correct boundaries. When you get a chance, you can re-run the SteamVR Room Setup to correctly setup your height and boundaries properly.
