Crisis Core Final Fantasy VII

[dimasok]

I have a question. I am playing it on a pretty good PC and there is very often a slight stutter/freeze (especially apparent before each "activating combat mode" transition). I played around with the settings and can't seem to make it stop. I also noticed that while this slowdown is happening, there is a hard drive access moment. Seems like caching to me. Other than that, the game runs smooth.

Not sure what is happening. Any ideas?
