Input lag

Its been almost a year! I used to play Minecraft Bedrock even with shaders at constant 60 FPs and I switched from Java to Bedrock just for better performance, and since Render Dragon came out, everything messed up and i started getting input lag and my mouse always stutters alot!

Im Disappointed mojang, my hardware is not so good but still i was able to play with no difficulty before and now its just messed up please fix these issues. I still use the same mouse i used to play before 1.16.200 so its not fault of any of my hardware its the software, Please fix This issue Mojang, a request from a Minecraft Lover!
