your GPU is very HIGH SPEC you realize and its a laptop theres a simple fix for this put it in to balanced or high performance now you need to know when on the go gaming really limits your play time with mine its about 2 hours... i learned that intel i-whatever number was an integrated GPU magnificent for media not so good for gaming(in certain cases) also on balanced your CPU has to operate at least at 50% of it processing capabilities(as in its speed not usage) it also allows you laptop by default to enable GPU automatic switching if your in power saver well it only uses the power saving gpu which means it uses the intel HDXX00(4000 most likely) graphics over the nvidia graphics and it won't switch either you can change it if you wish...
