What is wrong with my Minecraft [Bedrock]

Hello everyone I have a problem... the game is lagging very bad I only can play with 8 chunks and I've tried everything ( fresh drivers installation, cash cleaning, turning off 11 cores of my cpu bc google said that my cpu is having a stroke rendering minecraft with 24 cores, disabled HAGS etc.) When i use Rtx everything seem to work normally but with fancy graphics or vibrant visuals there's lags and stutters even on low settings.

In java I have more than 2k fps in vanilla Minecraft, but I do really want to play with my gf in bedrock I already bought the actions and stuff addon and so confused that bedrock work like that

My pc specs

Ryzen 9 7900x

Rtx 5070 ti

SSD 1 tb
