I am Quite sure that I will not have given enough information in one post for anyone to solve my problem so what I hope to acheive by this thread is a collaboration of possible solutions and maybe one of them will help me. Thankyou in advance to anyone that replies.

Recently I took up Dual Boxing on my laptop(More information is needed on this I'm sure but I don't know which information to give, so please, ask questions.), After doing this for a couple of days(2 wows on at the same time), I have noticed a dramatic decrease in the overall fps of my machine. It was store bought with no upgrades, aftermarket. One thing that may be noted is that I had let it get a bit hot(possible overheating issue) months before attempting to dual box. It never did overheat while dual boxing though. Now with 1 copy of wow running I am getting about 5-8 fps in dalaran, 15-20 anywhere else. Wintergrasp is not possible. I was used to 30-40 fps outside of town and 20-25 in, pre-dual-boxing.

If anyone has any sort of information to give or questions to ask, please, be my guest. I appreciate the help
