How to Allocate more RAM to Minecraft

Minecraft is a sandbox video game that was released in 2011 by Mojang. The game is among one of the most played online games and boasts a player base of 91 million players logging in to the game monthly. The game uses 1GB of RAM by default and it is disabled from using anymore by the launcher. There isn’t any lag on the game due to RAM mostly but if the users have installed custom textures and Mods the game gets laggy and users face screen tearing.
