I built my PC in June of last year with a GTX 960 4 gig and a FX 4350. Back when I started, It performed very well. Now though it appears to have slowed down significantly. the same games (GTA V, ROTR, The Witcher 3, etc.) perform worse with the same graphics settings. When I look at the Afterburner overlay it shows my CPU at or near 100% all the time, however when I go into task manager it shows only the game I am playing as any significant draw. This did not used to happen, so the question is: What would affect my CPU to make it perform worse in the same conditions?
