How to increase FPS in Minecraft and remove lags, optimize the game

In this guide, I will tell you in detail how to increase FPS in Minecraft, optimize the game, remove or reduce the number of lags, make the game faster and more comfortable, want to increase FPS in minecraft 1.16, 1.15.2, 1.14.4, 1.12.2, 1.7.10 and other versions?

What is FPS?
FPS (Frames Per Second) - the number of frames per second on the monitor screen that you see.
Simply put, everything moves in the game, mobs, grass, light, the player and your monitor displays all these animations by changing the picture on its screen, while a regular monitor changes the picture up to 60-75 times per second.
For a person, 24 or more FPS is important, with this value he stops noticing "brakes and lags", and 60 is considered a very comfortable level, but if the FPS falls below 24 - "hello lags"
Your PC should calculate and render the game and create between 24 and 60 frames for every second of the game.
The FPS parameter is affected by the performance of a particular PC, its processor and video card, but more on that later. Also, lags can be caused by incorrect operation of mods.
