When performing certain actions, I am experiencing frame jumps, sometimes minor, sometimes major. I'm quite positive that my computer is or should be capable of running Minecraft without these issues. Frame jumps occur when fighting (swinging specifically), creeper explosions, and sometimes even doors opening/closing.

I honestly don't know if this is a Minecraft bug or not. I did run a full scan and came up with nothing. I reinstalled Minecraft and that made the issue less common, but still occurred.
