but it did not happen with other games
and i checked it goes from 80+ fps to 20+ fps the moment i unplug the ac adapter
there is however the obvious option of batter battery/better performence function on windows 10 and i tried switching which didn't help
and also tbh i don't mind this thing since anyway i don't like gaming on battery power casue it eats through battery so fast used to play sc2 only when the ac is conncected but i thought i should report this bug
