Minecraft only using 40% of cpu and 20% of gpu?

[unaidedsteak]

hello! so recently ive been monitoring minecraft and i noticed something. it is only using around 40% of my cpu and 20 - 30% of my gpu. now its not like my framerates are bad or anything but the fps does seem to drop randomly and such and i do notice it. now is there a way to make minecraft use more resources so that my fps doesn't drop.

here are my specs just incase you want to know:
Core i3 2120 @3.4Ghz
Sapphire Radeon HD 6770
4Gb DDR3

Also it wouldnt let me post this in the Tech Support section sorry

Minecraft isn't really properly threaded so it's only going to use a single CPU core for the majority of everything, thus making it highly inefficient (and only able to use a portion of the total CPU power, hence ~40% usage). If you want to fix the periodic framerate drop you should add Optifine and set it to Smooth chunk loading (the Multi-Core setting seems to be buggy recently, though you can try it if you want).
