I just picked up a G75 yesterday and for some reason when i play skyrim it runs smooth for a few seconds, then hits a big spike. It repeats 5 seconds of smooth and 5 seconds of spikes the entire time i play. It does this for both battery saver and entertainment option. Also, where i am in the game doesnt effect whether it does it or not. I havent tried other games yet so no idea if its a problem on other games. Thanks!
