24/25p Playback Judder on M5 Vision Pro Due to 90 Hz Frame Rate Matching Issue

Platforms Vision
1

Hi Firecore team,

I am seeing what may be a refresh rate matching issue when using Infuse Pro on M5 Apple Vision Pro.

Device and software

  • Apple Vision Pro: M5 model, supports up to 120 Hz

  • visionOS: visionOS 27 Developer Beta 3

  • Infuse: Infuse Pro 8.4.8 (5690)

  • Confirmed playback mode: standard windowed playback

  • Full-screen immersive playback: tested, but active refresh rate could not be verified

Issue

During windowed playback, Infuse’s playback statistics consistently report:

Screen frame rate: 90.00 / 90.00 Hz

Example

The reported screen refresh rate does not change based on the frame rate of the video being played. This causes frame rate judder:

I tested multiple unrelated files from different sources:

  • 23.976/24 fps video → 90.00/90.00 Hz

  • 25 fps video → 90.00/90.00 Hz

  • 29.97 fps video → 90.00/90.00 Hz

Infuse correctly identifies the frame rate of each video, but the reported screen frame rate remains fixed at 90 Hz.

Full-screen and immersive-mode testing

I also tested the Full Screen option, which opens Infuse’s exclusive immersive playback environment.

However, the playback statistics overlay is not available once the immersive environment is entered. Because of this, I cannot verify whether the screen remains at 90 Hz or switches to a matched refresh rate such as 96, 100, or 120 Hz.

Expected behavior

I would expect Infuse or visionOS to use an appropriate display cadence for the source frame rate when supported.

For example:

  • 23.976/24 fps content could use approximately 96 Hz or 120 Hz.

  • 25 fps content could use 100 Hz.

  • 29.97 fps content can use approximately 90 Hz with a near-3:1 cadence.

The fixed 90 Hz value is therefore most concerning for 23.976/24 fps and 25 fps content, since 90 Hz is not an integer multiple of either frame rate. I can notice uneven motion or judder in some scenes, particularly during slow camera pans.

Questions

Thus, I wonder does Infuse currently request content matched refresh rates on the M5 Apple Vision Pro?

Also, can refresh rate matching be enabled after entering the full screen immersive environment?

I can provide diagnostics, MediaInfo details, or additional test results if needed.

Thanks.

@james Hi James, sorry to tag you directly, but this is currently the most disruptive issue with Infuse on Vision Pro, especially for slow moving scenes.

I have a few questions:

  1. Does Infuse currently request a content matched refresh rate in either windowed or immersive playback?

  2. Is proper framerate matching technically possible on visionOS, and is this something the team intends to investigate or fix?

I actively use Infuse across Apple TV, iPhone, iPad, Mac, and Vision Pro, and I really appreciate the work you and the team have put into making the experience available across the entire Apple ecosystem.

However, the visionOS version still feels behind the other platforms or other visionOS players in some QoL areas. I understand that Vision Pro has a smaller user base and that development priorities have to be balanced across platforms.

I am not asking for a firm release date. Even an indication of whether these issues are being investigated, planned for later, or unlikely to be addressed would be extremely helpful.

I am asking because these issues affect my daily use enough that I need to decide whether to continue relying on Infuse on visionOS or begin moving to another player.

I have also reported a few others:

Separate Ambient and Accent Lighting Controls for Vision OS Environments - Platforms / Vision - Firecore

OpenSubtitles “Download Subtitles” option missing on Apple Vision Pro - Platforms / Vision - Firecore

Bug - Version picker on visionOS truncates long version names and hides bitrate - Platforms / Vision - Firecore

Dynamic Ambient Lighting for visionOS Environments - Platforms / Vision - Firecore

Thank you again for all the work you and the team have done on Infuse. It remains my preferred player on every other Apple device, and I hope the Vision Pro version can receive more attention as well.
