How can I disable autosave since it is causing lag spikes?

Minecraft freezes so much that it is unplayable, even though I get a good 5 FPS at minimum graphics settings.

There is no option to disable "auto saving" option in minecraft, and I wish there is. Is there any way to disable auto saving? I have forge installed so I can use mods to turn it off.


You can't disable them, however you can change how often Minecraft autosaves with OptiFine.

Find the setting under Main Menu => Options => Video Settings => Other => Autosave Interval (bottom-most button).
