I've been getting huge frame drops In BF4 from 90 to 20-30 for 30 sec than It shoots up to normal
Also GW2(Crappy performance as well which shouldn't be happening with my graphics card) And In Gta V. Witcher 3 runs well on max settings except Hair Works I get mid 40's to 50's and low 30's sometimes 60.My computer shuts off randomly and restarts sometimes but It hasn't been doing that recently.
