So i'm playing games (LoL), and I accidentally unplug the charger. The FPS drops from ~80 to ~30. Is this because the change in brightness because when the laptop is on battery, the brightness seems to change every once in a while. Is this supposed to happen?

I have an HP Envy 17 with Intel i7 4700MQ, 16 GB RAM, NVIDIA GeForce GT 740M, Windows 8.1 Pro.

Is there anything I can do in settings to not have it change?

Power settings. Change the settings for 'On Battery'.

I checked in my power settings are the brightness is same on both on battery and charging. I am positive it is the right power plan.
