So, you have a very powerful system, but you're also emulating a non-trivial title on top of a 60 FPS hack (huge speed down) and with a texture pack (small speed down, but mostly likely cause of stuttering problems for many users)
Since you got the same slowdowns with lower IR, it's probably not a GPU issue.
Since it ran at full speed without the 60 FPS hack, that is likely the cause. Your system probably just can't handle all parts of the game with the hack.
60 FPS hacks aren't to be underestimated in how intensive they can be to use.
