Minecraft optimisation

So, I've played both java and bedrock and they're amazing games everything works fine, education and real life mechanics for studies too. But, they're both not optimised well, Mojang always brings exciting updates but never done something about running the game smoothly, even the vibrant visuals can't work on low performance devices (mobiles, tablets and even bad computers). I'm not telling anything bad to the game or Mojang I just want you to see my post which I'm typing right now and work for optimisation in both versions. It's very much needed that a game runs nicely so, please do something about it as soon as possible. Thank you. :)
