Use the latest version of OptiFine mod. Close all other programs and only keep Minecraft in your computer. Disable unnecessary resource packs. Allocate more RAM to Minecraft. Clean the dust in your desktop host, like CPU heatsink and power supply fan. Rely on third-party program like CCleaner. Get a better computer.
