So, as the title says. I play league from time to time with the wife and recently I noticed my fps dropping from 400+ to 90+ and everywhere in between. I've tried to cap my FPS at 120, helps with jerkiness of the ups and downs but it does not stay locked there. It'll go all the way down to 80+. I've reinstalled drivers, reinstalled the game and even did a reinstall of Windows... why not.
