When I play games with my laptop plugged in, the games run great. In csgo I get about 120-130 fps, but as soon as I unplug my laptop I only get 20 fps. Other games run smoothly when it's plugged in, but as soon as I unplug it they only get like 9 fps. My power plan for the laptop when it's not plugged in is on high performance and everything is at max. When I look at my performance it says my cpu is running at 3.70 GHz. I don't really understand why I'm getting low fps if everything is at max? Can anyone help? Thanks
