You wouldnt believe the stress im suffering with this ;(
Month ago, stutter after a while in intervals, fps going from 60 to 20 for some seconds and then again to 60. Had 4gb ram in 2 sticks, removed one, added a 8gb stick, problem persisted.
It started with a gtx 750, bought a R9 380 4gb the other day, problem still there but worse now.
Every game runs smooth as butter for some minutes, then a small stutter, then smooth again, then the stutter is more frequent until the point I need to close the game because it starts to literally freeze for seconds.
I already knew this was because gpu usage dropped insanely to 20% (even with the 750)
Today I noticed that the core clock is suffering drops. In intensive graphical situations it stays at 800/900, but after a while it starts to fall to 500/400, with the consequent atrocious stutter.
In many places I readed that psu could be the cause, but other people say that if the psu its not enough the pc just crashes.
Tried the uniheaven engine benchmark (or whatever is called) everything at extreme/ultra settings, I cant reproduce the issue, moving the camera like crazy and running all over the place, constant 60fps (that benchmark is gpu dependant, cpu is always super low)
I just dont know what to do anymore.

INB4:
cpu temps never above 50°c (using a nice cooler)
gpu max temp 75°c (its normal for that gpu), just in case increased the fans speed wih afterburner: max temp was like 55....stutter was still there.
Tried A LOT of things, nothing fixes it.

HELP
 


Have you tried reinstalling the Drivers for your GPU?
 




Installed the new card with updated drivers, then reinstalled windows 7 from scratch with updated drivers again, issue still there.

 
Did you ever fix this issue? I have a 380x and I'm having a similar problem so I'm looking for a solution. It used to run Witcher 3 beautifully at 60 fps now frames drop all the time.
