yeah,
i wouldnt too
cause it works before for me too
but i tried and it works now and i am glad (but the issue for you is another like i said prob)
how warm is your PC getting on CPU and GPU playing D4?
my cpu can get 80 in towns if alot of people there, i use one of AMD highest cpus,
in other towns its normaly around like 66 70.. and while playing pits etc etc around 72-78.
"Acording to HWmonitor stats"
GPU seems to stay around 60-68 while smashing monsters.
