Game stutters

Hello, i have been using minecraft education at school and at home for when we do something we could not do at school. For this i use my home computer for what i thought would be better performance but instead, it starts to stutter a few seconds after joining a world and it becomes progressively worse within a minute and it becomes unplayable. I do not have this issue on my school laptop. I also own actual minecraft for when i play with people that do have the official version. When i play that, no stuttering just smooth gameplay

In case it is needed my PC Specs

-GPU, GTX 1080
-Processor ,AMD Ryzen 5 3600X 6-Core.
-RAM, 16 GB, Unkown brand/version.

Things to note,

I did not always have lag, it only started more than a month after i started using it and has been lagging ever since.
