Severe FPS drops and performance degradation following Update 26.12

Since updating to Bedrock version 26.12, I have experienced a significant decrease in performance. Even with "Improved Input Response" turned OFF, the game suffers from constant stuttering and a much lower average FPS compared to version 26.10/26.11.

​Steps to Reproduce:

​Launch Minecraft Bedrock Edition (Version 26.12).

​Enter any existing world or create a new one.

​Observe frame rate during normal gameplay (moving, breaking blocks).

​Observed Results:

Frequent lag spikes and consistently low FPS that make the game feel sluggish and unresponsive.

​Expected Results:

Performance should be stable and comparable to previous versions (26.10).

Disclaimer: It was working well before this update almost no issues second i updated it and opened my world immideatly noticable stutter.
