I have a GL703GM, myself and a couple of others have had the same problem. I thought i had it solved but today it seems to have returned with reinstalling Steam, CPU's seem to be overheating and battery draining. I had this issue playing counterstrike, I optimised the settings for Counterstrike in 3d settings so will try that again and see if it solves the issue, though may also be due to latest graphics driver update. Will advise once I've rest everything. But yes seems to be an issue with the laptops as they cant run on full settings without battery draining.
