GPU : Palit GTX 660 OC Version 2GB DDR5
CPU : Intel 2 Quad 9550
PSU : Corsair VS650 - 650W Single +12V 54 amps
SSD: Crucial MX200
Note : The problem occurs only with the new gpu i installed when i switch back to my 9500gt the problem is solved
Note 2 : Even using gtx660 without its driver is working without any DPC latency so the problem occurs only when i install its driver
Note 3 : Using Latencymon i found out that the drivers that producing the DPC Latency are nvidia drivers nvlddmkm.sys and dxgkrnl.sys
Straight to the point, i installed a new GPU GTX 660 to my computer and i am having insane DPC latency like horrible audio quality with cracking pops clicking sounds, like mouse lag especially when using mouse wheel the pc sounds like its gonna crash
The weird part is when i open GTA V ( A very modern game with very hight system requirements ) i run it with pretty good performance and FPS
Same goes for 3D Mark benchmarks and Stresses
I mostly notice the DPC problems in Youtube 1080p videos and in casual pc usage rather in gaming
In gaming i mostly notice fps drops and the weird part its that when an FPS drop is taking place at the same time the GPU Usage drops thats weird right?
it would make more sense that fps drop + higher gpu usage rather than lower gpu usage
I contacted nvidia they could not help me they only asked me to do some tests to the gpu to see if its defective Like stability tests benchmarks etc. which all worked
then they asked me to try the gpu in another pc which i dont have one so the communication with them stops there
Things i tried :
Older driver versions, reinstallation of the drivers etc.
Google image to show you how my dpc looks like when i am watching a youtube video :
