Oculus Air Link Laggy / Stuttering? (11 Ways to Fix)

Trying to enjoy some wireless PCVR gaming with Oculus Air Link, but simply can not get optimal performance out of your setup?

You are definitely not alone! To help you out, I did some testing and research on my own to find the most common issues and solutions to Oculus Air Link performance issues.

So if your Oculus Air Link is laggy or stuttering, here are the most common steps to solve the issue:

  • Use Ethernet Cable to Connect Your PC and Router
  • Use a Dedicated 5GHz WiFi Network
  • Be Close To The Router
  • Fine-Tune Your Router Settings
  • Set Encode Bitrate Value to 0
  • Raise OVRServer_x64.exe Process Priority
  • Update Windows and GPU Drivers
  • Adjust Oculus Graphics and Refresh Rate Settings
  • Manually Adjust Air Link Bitrate
  • Purchase Dedicated Router
  • Contact Oculus Support

Let does next look at each of the steps in a bit more detail.

Note! Before jumping in, make sure that your PC meets the requirements for Oculus Air Link. If your PC specifications are on the lower end, you might just have to accept that for some games, you simply won’t be able to get optimal performance.

1) Use a Cable to Connect Your PC and Router

The first step for optimal Air Link connection performance is to make sure that you are using an ethernet cable (CAT 5 or 6) to connect your PC and router.

Sure, some people may claim that they are able to use Oculus Air Link by using WiFi in both the PC and headset. Good for them.

Since you are having performance issues I recommend doing it the right way from the start and use an ethernet cable instead of a wireless connection.

If the router in your house is too far away from your PC, you really might want to consider purchasing a dedicated router for your Oculus Air Link.

2) Use a Dedicated 5GHz Wifi Network

Ideally, you want your Quest / Quest 2 headset connected to a dedicated 5GHz network that no other device in your home is using.

So when also taking into consideration the previous recommendation, the topology of an optimal Air Link setup might look something like this:

Most modern routers support dual-band connections (2.4GHz and 5GHz). Quite often it is the case that both frequencies are used concurrently within a single SSID (Wi-Fi network), leaving for the router to decide which connection to use.

Oculus Air Link works best with a 5GHz network connection. It would therefore be a good idea to create separate 2.4GHz and 5GHz WiFi networks (refer to your router manual) and only connect your headset to the 5GHz WiFi network.

3) Be Close To The Router

Another critical factor when you want to get low latency and stable Air Link Connection is to make sure that you are close to the router.

Ideally, you want to have the router in the same room where your play area is (with straight visibility to your headset). Raising your router off the ground (at least 1m) is also recommended for optimal signal strength.

You might get away with the router being in the room next to you, but too many walls/obstacles between your headset and router will certainly diminish the network signal strength and connection stability.

4) Fine-Tune Router Settings

Oftentimes getting the basics right, is enough for a good and stable Oculus Air Link performance.

If this is not the case for you, you might want to dive into your router`s settings (refer to the manual) and make the following changes (if applicable to your specific router):

  • Change network mode to 802.11ac or 802.11ax only
  • Find and use the least congested Wi-Fi network channel
  • Change channel width to 40 or 80 MHz
  • Disable Smart Connect
  • Disable Quality of Service (QoS)

I have discussed each of these configuration aspects in a bit more detail in my previous article.

5) Set Encode Bitrate Value to 0

If prior to using the wireless Air Link you have also used the regular wired Oculus Link, you yourself might have caused the current performance issues.

The thing is that for regular Oculus Link, it is often recommended to play around with the “Encode Bitrate (Mbps)” value in the Oculus Debug Tool to get the best performance and quality out of your setup.

For Oculus Air Link, leaving the Encode Bitrate anything other than the default value (0), is likely to cause severe lagging/stuttering issues.

You can find the Oculus Debug Tool from “C:\Program files\Oculus\Support\Oculus-diagnostics\”. Check that the Encode bitrate value is set to 0 – if not then change it back and test your Air Link connection performance again.

6) Change OVRServer_x64.exe Process Priority To High

In my previous article about solving Oculus Link performance issues, one of the recommended solutions was to raise the OVRServer_x64.exe Windows process priority to High (or Realtime).

This technique also applies to Oculus Air Link and has been reported to fix (or at least significantly improve) the performance issues people were having.

So go ahead and try raising the process priority by following these steps:

  1. Open “Windows Task Manager” (CTRL+ALT+DELETE)
  2. Navigate to the “Details” tab
  3. Find OVRServer_x64.exe process
  4. Right Click and “Set priority” to High or realtime

Do keep in mind that you have to change the process priority each time you restart the computer or exit / disconnect the Oculus Link software.

7) Update GPU and Windows Drivers

With Oculus Air Link lagging and general performance issues, it quite often comes down to the graphics card and the drivers you have installed.

Make sure that you have the latest drivers installed for your graphics card. However, also do keep in mind that in recent times there have been problems with the latest driver releases causing performance issues (e.g for Nvidia 30xx series).

The incompatibility issues, if present, have been usually solved very quickly.

Additionally, make sure that your Windows OS is up-to-date and test the performance of Air Link again.

8) Adjust Refresh Rate and Graphics Settings

When facing performance issues, it’s almost always a good idea to start with the lowest settings and move upwards from there.

  1. Open Oculus Software on your PC
  2. Go to Devices and select your headset
  3. Select “Graphics Preferences”
  4. Set the refresh rate to 72Hz
  5. Toggle the “Automatic” option for “Rendering Resolution” off
  6. Decrease the “Rendering Resolution” to the minimum value

If this combination gets rid of your lagging issues with Air Link, start raising the values and find the optimal graphics-performance ratio that best fits your preferences.

9) Adjust Oculus Air Link Bitrate

By default, Oculus software will automatically determine and adjust the Air Link bitrate value based on your network and router performance.

In most cases, this will also provide you the optimal performance-quality ratio.

Mainly for troubleshooting and problem isolation purposes, it is worth setting the bitrate to a low fixed value. If this fixes your lagging issues, there might be unexpected traffic congestion and/or interference in your network.

It is also quite likely that the problem might be caused by the fact that your current router is just not good enough for wireless VR gaming purposes.

10) Purchase Dedicated Router

If you have tried everything up until this point and nothing seems to solve your Oculus Air Link performance issues, my recommendation is to purchase a dedicated router for your Air Link setup.

Some routers (especially the older/cheaper ones provided by your ISP) are simply not cut for this purpose.

If you are willing to make the expense and wondering which one to buy then luckily most modern routers will do just fine. If you want to be sure, these 3 routers are recommended by Guy Godin, the lead developer of Virtual Desktop (the go-to software prior to Air Link)

The setup of a dedicated router is really not difficult at all. You just connect your main router with the new dedicated router with an ethernet cable and configure it to be in “Access Point mode”. The basic topology of the setup is shown in the image below.

If you are unsure, this Youtube video lays out pretty much a step-by-step guide on how to set up a dedicated router for wireless VR gaming.

11) Contact Oculus Support

As the last resort, I recommend creating an Oculus support ticket. When creating the ticket, make sure to include

  • Your PC specs (CPU, GPU, RAM)
  • Logs from the last 24 hours
  • Description of your setup and a list of steps you have already taken to solve the issue.

When including a detailed description of your problem upfront, you`ll have a much higher likelihood of getting adequate response from the Support team and getting the issue solved more quickly.

Dedicated Router For Wireless VR

Wireless PCVR gaming does not have to be expensive! TP-Link AC 1200 router (reccomended by Guy Godin, developer of Virtual Desktop) has proven to offer excellent performance at a reasonable price!
