Hello friends,
So I have these high DPC latencys on what seem to be Nvidia drivers. I'm not really sure how to interpret these results, tried searching around for answers, but the only thing I could gather was that people whose same drivers that caused high DPC latency has audio drops/crackling, which I thankfully do not have. I have for the longest time though experienced stuttering in some games (not all), even some simple 2D side-scrolling games which you'd think my computer would be able to handle no problem stutters, which is just strange. Not sure if all that stuff is related to these drivers acting bad. I have the latest Nvidia drivers and the last BIOS version. I used latencymon for the diagnosis.
Computer specs are:
Windows 7 64-bit Professional
Gigabyte Z97X-UD5H
Intel I5-4670K
Gigabyte Geforce 760 GTX
8 gigs corsair ram
Samsung 250 gigs SSD
650 watts XFX power supply
Any help is greatly appreciate. Please let me know if you require more info.
Also, here's the conclusion:

CONCLUSION
_________________________________________________________________________________________________________
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 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 0:04:41 (h:mm:ss) on all processors.

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): 2634.063827
Average measured interrupt to process latency (µs): 4.845249

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.
Process with highest pagefault count: chrome.exe
Total number of hard pagefaults 4491
Hard pagefault count of hardest hit process: 4372
