So I have a server for me and my friends in minecraft bedrock edition, we all play at android devices some of them plays in PC, there are 20+ of us. So before we used to play with high quality texture pack (I dont use shaders, maybe some of my friends uses it) and high render distance  [like 6-9 render chunks] and also all of toggles in our video settings are toggled, we get 30-60 fps [not exact only my calculation since its smooth]  when we are playing, it is smoother when texture packs are off. Its version was 1.18.12 and then after we updated to 1.18.30 things have changed. Even though we are on lowest render distance and removed our texture packs we only like run 10 fps or maybe lower.

The game is literally unplayable, Killing the ender dragon is impossible with the framerate, I played on singeplayer its still the same, I tried playing on my PC since I also have minecraft bedrock there, It kinda became slower by a bit. Most of my friends stopped playing minecraft and they said they will just wait if maybe mojang fixes this type of problem. I hope that this problem will be solved.
