fps drop in games :s

[100%scottish]

I bought an iphone after swearing a few years ago id never own one and obviously to sync music etc I had to install itunes. now in certain games (nfs shift, shift 2, mw3 etc) my fps drop to an unplayable level. this just happens randomly for example in shift I can sometimes get a few laps in before this starts. I have tried stopping all processes apple related in win optomiser 8 but still no luck. help very much appreciated! (specs are in sig)

Extremely unlikely to be Apple related, check your event logs for anything else which could be causing it. If in doubt take iTunes off but I've never seen it cause this.
