Severe system slowdown after launching Minecraft Bedrock Edition

Steps to reproduce the issue:

  1. Launch Minecraft Bedrock Edition after the latest update.

  2. Try playing normally for a few minutes.

  3. Observe system performance.

Expected result: Minecraft should run smoothly, and the operating system should remain responsive.

Actual result: After a few minutes of gameplay, the entire operating system becomes extremely sluggish, including Minecraft itself, which drops to around 3 FPS.
Interestingly, RAM, CPU, and GPU usage remain normal—no spikes are detected.
Troubleshooting steps taken:

  • Removed all texture packs.

  • Ran the game as administrator.

  • Ran the game via double-click as usual.

  • Restarted the computer.

  • Launched the game from the Minecraft Launcher.

  • Launched the game directly without the launcher.
    None of these actions resolved the issue.

Latest Bedrock update completely broke the game — unplayable performance despite normal resource usage

Please attach a screenshot of the Minecraft process in Task Manager when the system slowdown is occurring.

I have the same thing, prior to update the game was running smoothly, and I’ve got a gaming laptop with the 13th gen of I5 and RTX 3050ti, the game becomes very sluggish and laggy when I enter any world on bedrock, even when I leave the world minecraft’s menu becomes laggy as well. Another thing i’ve noticed is that when I leave the game I can still hear the sound of minecraft’s main menu for like a minute or so, it did not happen prior to update.

I got the game playable again by turning off the “Improved Input Response” toggle under the Video settings. There is still a bug that needs fixing.

that is not the case, I have Improved Input Response disabled but my minecraft has a very severe slowdown after the update..

Although It is also a memory leak

Never mind I reopened the game with Improved Input Response and it is the right call to close this
