I've been noticing frame drops in games such as nioh, tekken 7, bf1 and other games. Was wondering what could be the problem, I've monitored the temperatures for many games and they don't seem to be overheating, gpu at most at 60-70 and cpu 40-50. I see some noticeable cpu usage drop to like 30% to 10% when before it was usually much higher for bf1 which I think is cpu intensive. Just wanna know if it's something else to do with my general specs or if it's a cpu/gpu issue because this is basically my second build and the same thing started happening to my first build. Also a buzzing noise from my pc has begun happening nothing too loud, but enough to notice it since getting these frame drops.
