I've been playing Minecraft since 2010 and I switched to the bedrock engine as soon as I got to know about it because the fast system requirement increase that Java edition went through.  System requirements increased a lot under a year for bedrock edition as well! Way too much and that's a problem. It became quite frustrating and it happens once out of five cases that we get in a situation that causes our death in-game because of the stuttering caused by the system requirement increase. Until 1.14 release Minecraft Bedrock edition was much much smoother, faster and overall felt more fluid than Java edition ever because of the C++ coding and different engine.  This worked on Android (Redmi Note 4X and Realme 5 Pro) and PC (desktop and Laptop[Dell Vostro 15-3568]) [config specs attached of desktop device] until 1.15 release when noticeable performance issues appeared on all the four devices. When the nether update arrived with 1.16 performance became a lot worse... I even did a clean reinstall on both PC devices suspecting OS issues but that didn't help either. We (my bride, me and her nephew) stick to the bedrock edition because the supposedly easier online game and smoother gameplay. Couldn't one do something about this ridiculous performance increase? For Java edition there's optifine at least which helps but for bedrock edition and cross device gameplay I know no such mod or addon or whatever that could help and that's why I'm writing this official bug report. Thank you for your time and effort.
