Hola !
I just wanna start off with some short backstory; I have been playing Diablo 3 since release and ive always had "stutterlags", but i just wrote it off as old hardware (mostly the graphic card).
A week ago i got really tired of it and bought a GeForce GTX 980 Ti. But the stutterlags remained!
So i started looking in to it. With LatencyMon i saw that i had alot of DPC spikes, with over a week now doing whatever solutions ive found on google i still havent figured out the problem.
Hardware:
P8Z77-V PRO
Intel i7-3770K (Ivybridge)
Gigabyte NVIDIA GeForce GTX 980 Ti 6GB G1 Gaming
16GB DDR3 (Corsair Vengeance LP CML 16GX3M4A1600C9)
Corsair Force 3 SSD (and two regular western digital harddrives)
Corsair TX650W Power supply
And i use Windows 10 64-bit.
Things ive tried so far:
Changing from Windows 7 to Windows 10
Updating BIOS
Disabled EPU Powersaving mode, Sidestep, Turbomode & C1E in Bios
Disabled/Enabled HPET
Disabled/Enabled NIC & Soundcard
Set all power options to max
Updating every driver imaginable
Switching PCIe ports for the graphic card
I let LatencyMon run idle for 10 hours.
Stats here:
I also had high ISR count on: dxgkrnl.sys , storport.sys , HDAudBus.sys & USBPORT.SYS
Im pulling my hair out on this one, i would really appreciate some help :)

Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 10:08:59 (h:mm:ss) on all processors.

Computer name: DESKTOP-0PS28RR
OS version: Windows 8 , 6.2, build: 9200 (x64)
Hardware: ASUSTeK COMPUTER INC., P8Z77-V PRO
CPU: GenuineIntel Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz
Logical processors: 8
Processor groups: 1
RAM: 16327 MB total
_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 3518 MHz
Measured CPU speed: 1 MHz (approx.)
Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.
WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 609,738706
Average measured interrupt to process latency (µs): 1,843041
Highest measured interrupt to DPC latency (µs): 607,992437

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
