What was supposed to happen was the game when loading a new world or when loading a game on a server it crashes or the fps drops and the chunks don't load.

What I expected to happen was the world to load and be slightly slow to begin with but still be able to move around and play the game as normal and the game on any server to load and be able to move without lagging or with only a bit as chunks load.

What actually happens is it lags as soon as the world starts to load in and does not get better with time, I can barely move around and chunks barely load its the same with being on a server and joining a game.

I have done everything any website such as planet minecraft has suggested but there has been no prevail.
