Skipping/lag

Every 5 minutes or so my game starts to skip then it kinda pauses skips a few more times then either completely freezes or just crashes. Whats going on? Is this because of the new update cause since then Ive had nothing but problems. I absolutely love this game but if this keeps up I dont think Ill be playing anymore, which makes me sad.
