Minecraft – Allow Minecraft to Use More CPU

minecraft-java-edition

A lot of people seem to be having problems with Minecraft using too much CPU power. I wish for my Minecraft to use more CPU that it does now.

Some Info: I have a dv7 laptop with an i5 quad core 2.4 gHz chip, 6 GB of RAM, and a Radeon HD 6770 graphics card. Basically, this computer is quite the beast. It can play Eve and other high-tech games. But it plays Minecraft slower than my brother's computer, which is dual core and equipped with a low-end graphics card. I asked him to open his task manager and found he was using 60%, if not more, of his CPU to play Minecraft, exceeding his performance.

Question: How do I enable my CPU to use all its cores and CPU power on Minecraft?

(Unmodded) Minecraft isn't multithreaded, so splitting it across multiple CPUs is not possible. However, I am not sure about a mod to allow for this possibility. There might be other factors you are ruling out.

From what I have found the mod, OptiFine, is supposed to split the load across two cores. (Otherwise, Minecraft only uses one)

OptiFine 1.2.4 Mod adds a lot of options for better looks and performance. Doubling the FPS is common. Moves fog away, adds mipmaps, chunk loading control (mod CAF), Smooth FPS, brightness control, VSync and many other.
