Just this morning I was playing CS:GO with around 150 fps constant medium to high settings and about 140 fps maxed out settings on league of legends and I turn on my PC about 4 hours later and I'm struggling to get 60 fps with lowest settings on both. (my temps are fine and downloaded latest drivers).
