Hi! Recently I've started to experience random, massive drops in FPS, going so low as to 5-10 from an original FPS of 60-100. This persists for a few minutes, then goes back to the normal FPS, and then drops again. I've updated my Nvidia drivers, though it's done nothing to abate the issue. I'm not particularly technically inclined, so I hoped I could find a solution to the problem here.
Below I've added images of HWMonitor statistics during both low and high FPS.
