iOS: Main menu has extreme lag (FPS drops) when offline

When offline (not connected to a Wi-Fi connection, not on data, or airplane mode is activated) the main menu faces extreme lag. However, this lag does not occur when you get in to a world (this does take a considerable amount of time.) This happens on both my iPhone and my iPad, which are both on the latest stable versions.

List of affected devices:

  • iPad Pro 2018

  • iPhone 12

  • iPad Air 11” M2 (started to occur after updating to iPadOS 26, according to duplicate report)

  • Could you please let us know if this issue persists after the latest update?

  • Could you also give repro steps to reproduce the issue?

This ticket will automatically reopen when you reply.

The issue persists in the latest stable build 1.21.81. Simply turning off any sort of connectivity before opening the game causes the issue to occur.

I have tried turning off Wi-Fi, turning on Airplane Mode while Wi-Fi is off, signing out of my Microsoft account within the game before turning off connectivity and all of which lead to the bug still occurring. This happens on both of my iOS devices (iPad Pro 2018 and iPhone 12) but I don’t have any other device to test this on, so I’m unaware of the status of this on other Bedrock platforms.

To reproduce the issue, I’ve found that just turning off your system’s Wi-Fi before launching the game causes the issue to occur.

This bug also occurs on the iPad mini (A17 Pro)

Still an issue over a year later which is ridiculous. Completely prevents playing the game remotely as loading into a world is next to impossible when there’s no cell service.

iPhone 17. iOS 26.5.1

MCPE version 26.33

I can’t just believe it it’s been a year. Update after update and still this issue is not addressed.

I had hope that one day I will play offline but I don’t know now…

Device: IPhone 15

iOS Version : 26.5

Mcpe Version: 26.33

The root cause is precisely the high complexity of the RenderDragon engine itself (such as its resource loading mechanisms), which on iOS manifests as overwhelming Metal’s command submission, and on Android similarly overwhelms Vulkan or OpenGL.

On iOS (iPhone 13, A15), this overloads the Metal command buffer, leading to severe GPU stalls. China netizen observed frame rate as low as 0.5 FPS

All versions that include the Render Dragon engine are affected. Players experience latency spikes when generating chunks, as well as during turning and movement.
