OCULUS LINK: How To Increase Image Quality Of PCVR Games On Oculus Quest 2
In order to get the most out of the Oculus Quest 2 screen, here’s how to increase the visual quality of PC VR games with the Link.
The Oculus Quest 2, like the first model, has the Oculus Link feature allowing it to access the Steam PC VR games catalogue and the Oculus Rift store.
The service, now used by many players, however, does not transcribe the best image of the games when used with the original settings
Released from beta in November 2019, this unprecedented feature has just propelled the Oculus Quest 2 to the first place of the most used virtual reality headsets on Steam (see article). This shows how the Oculus Link has found its place among PC VR players.

Oculus Link: Which USB Cable To Choose?
To get started, it is recommended to choose a quality USB 3.0 cable to obtain a sufficiently high speed. Oculus of course offers its own model, however, it is possible to find other USB cables much cheaper and just as powerful. Here are some alternatives:
The one we recommend: Anker USB C Cable, Powerline USB 3.0 to USB C Charger Cable (10ft)
Quality And Functionality Of The Oculus Link
To fully understand, it is important to know that the image broadcast in the Oculus Quest is nothing other than a stream of the game running on the PC.
To avoid any latencies, compression is applied to the video signal so that it can be transferred as quickly as possible to the virtual reality headset.
Unfortunately, the impacts of this compression are multiple and result in a slight degradation of the image.
In fact, we notice in particular an increase in blur as well as a reduction in the colour range (duller image and less faithful colours).
To realize the differences, here are two comparisons on Half-Life: Alyx. On the left is the original source and on the right is the Oculus Link version. To better distinguish the differences, the image has been zoomed to 200%.
STEP1: Oculus Link: How To Improve The Quality?
Since v23, the Oculus PC application has provided additional settings for the Oculus Link. To display them, go to the “Devices” menu, select “Quest 2 and Touch” then in the right pane click on “Graphics preferences”.
From there, and depending on your PC configuration, you can start to change some parameters by starting by switching the frequency from 72 Hz to 80 Hz, or even 90 Hz which will bring more comfort. On the other hand, to get a finer image, you can increase the “Render Resolution” slider up to 1.2 (3920 x 1984). It is of course possible to push this setting further, however, be sure to monitor the latency which may gain traction. Note that Oculus does not recommend going beyond 1.6.
How To Use The Oculus Debug Tool
If the image now gains somewhat in sharpness, the most observant will notice that the compression effect remains present.
The cause of this stems from Facebook’s limitation on bandwidth. By default, this would be around 150 Mbps. Fortunately, this limitation can be removed via the Oculus Debug Tool.
The tool is located in the Oculus application installation folder on PC, by default:
"C:\ Program Files\Oculus\Support\oculus-diagnostics\ OculusDebugTool.exe".
A must-have for hackers, the Oculus Debug Tool once made it possible to modify the graphics preferences mentioned in the previous paragraph before they officially appear in the application.
You guessed it, the part that interests us concerns “Encode Bitrate (Mbps)”.
This setting is the most important because it will drastically reduce the degradation of the image caused by the compression. But then again, the value is going to depend on the power of your PC.
At 250 Mbps, the difference is seen considerably thanks to a much clearer picture. If the experience remains smooth, without stuttering, you will be able to increase up to 300/350 Mpbs. Even if it is possible to go up to 500 Mbps, the difference will be imperceptible and you will gain in latency.
For the values to be fully taken into account, the Oculus application must be restarted for each modification. To facilitate the task, a shortcut is accessible by clicking on “Restart Oculus Service” in the Service menu.
- Right-click Oculus Runtime Service.
- Click Restart. It will likely take a moment to finish
