The optimization in this official version of minecraft bedrock is unstable...
Comparing it with the previous official version 1.18.12, the optimization has worsened by 30% causing some FPS drops.

From 120 FPS to 90 FPS with which I was running the game, now they decreased to about 60 to 55 FPS and worse still, with sudden drops of about 15 FPS.

They continued to fix this soon since the gameplay experience is lousy
