Default A hesitation/stutter/lag in gameplay with SnowJB rom and Mysteryemotionz 6.1

I have SnowJB rom and Mysteryemotionz 6.1 kernel and it seems like every now and then when playing a game I get a quick freeze/hesitation in gameplay. A good example is in Asphalt 8 when I cross the finish line of the very first track. Almost every time when I cross the finish line there is a stutter or hesitation of the gameplay graphics. This seems to happen every 30 seconds in games. Is it the rom, the kernel, a game loading problem, other apps causing this, leftover interference from other roms, a hardware issue? Anyone know this, how to fix this? Thanks.
