Comparison of the new OFXR Bridge FrameGen with Virtual Desktop SSW.

Tech differences:

1. OFXR Bridge FrameGen (v0.2.13.2) – frame interpolation tech (OpenXR only).
2. VD SSW – frame extrapolation tech (Fully universal).

Have you encountered this issue?

Previous builds (such as v83.0.0.333.349) handled H.264 @ 500 Mbps, set via the Oculus Debug Tool, smoothly - even wirelessly.

Since the Link app update, going above 200 Mbps causes extreme compression artifacts (it looks like ~5 Mbps).

How to reproduce the bug:

1. Update the Oculus Link app to the latest version (v206.0.0.109.432, for example);

2. Open the Oculus Debug Tool and manually set any "Encode Bitrate" value (for example, 300-500 Mbps);

3. Start an Oculus Link session - everything will look extremely muddy, and Windows Task Manager will report that streaming is only using ~15 Mbps;

The only way to eliminate the bad quality on newer versions of the Horizon Link app is to set "Encode Bitrate" in the Oculus Debug Tool back to "0" and restart the Link session.

Also worth noting: on the newer Oculus Link app (v206.0.0.109.432, for example), you can no longer change the bitrate via the Oculus Debug Tool on the fly. You have to restart the Link session for the changes to take effect.

Returning to the main issue:

Since you can no longer use manual bitrate settings via the Oculus Debug Tool, you can no longer use a bitrate higher than what the Oculus Link app provides in its settings (200 Mbps is the limit as of August 2026).

Previous builds of the Horizon Link app (such as v83.0.0.333.349) easily handled H.264 @ 500 Mbps when set via the Oculus Debug Tool - even wirelessly. The bitrate could also be changed on the fly.

I'm not the only one experiencing this issue either - at least a few people on the other forums are reporting the same problem.

Warning: By doing this, you will lose your head strap warranty, so only perform it at your own risk.

Instruction:

1. Eject top left soft pad by pressing the release;
2. Unscrew the nearest first of two screw;
3. Unscrew the second screw at the bottom;
4. Gently open face plate;
5. Gently push with a flat screwdriver head into the little black box near the fan adjust roll;
6. Check, if it worked for the first try, or do you need to push again to complete.

This way, you effectively destroy the speaker, and it no longer will bother you again.

In my case: I've done this several months ago. Since then everything works fine. After this procedure I don't anymore hearing annoying loud beep, every time I installing the battery on the strap. I only hear battery charging sound from the Quest 3 itself.

Since I usually always use the fan - I also always notice when the fan goes off, when the battery is drained and need to be replaced.

So for me, personally, it's only the positive.
