I'd like to provide an update on the issue.

It seems that initially the game was switching to Intel(R) when on battery. I have managed to make it stay on GeForce GTX card, but once more the game is having dip spikes and drinking up battery and heat. At this point I'm unaware if this is a game problem or as a whole a system problem. I'll update my Windows and get some other support. Sorry and thank you.
