    Hey all. Need some help. I just did a fresh install on 1903 and I am getting some weird stutter going on. In games I'll be going along at say 100+fps then all of a sudden it'll drop down to like 80ish fps and stutter horribly and it does it anywhere between every 30-60 secs. It not only is doing this in games but also while I am surfing the net(as I type(every 30 or so secs) it pauses and takes it a lil to show what I typed)). Youtube videos stutter and when I scroll web pages it pauses(My desktop even pauses/stutters). I just can't figure it out. I have tried many of the latest video drivers and I've taken the OC off of both my gpu and cpu, but it still does it. Sooo, in short no matter what I'm doing my computer pauses and it is driving me CrAzY!! Any ideas? If you need more info just ask away. My rig is in my sig. Currently running Hotfix 430.97.

    Also you can spy on CPU usage in Task Manager while watching videos or browsing.

    Well I started that LatencyMon program up and let it run and left for a few. Came back and this is what it was saying after a lil over 19 minis. Not sure where to start. I tried that CPU throttling thing it said but not seeing it....

    Latencymon can copy a text report into clipboard (in menu Edit), so you can paste your report here.

    Ok I'm back. Well while I was waiting, I did some searching and came across this article on "How to disable Power Throttling in Windows 10". It's almost a couple of years old, but what it said to do worked!!! 1st I tried disabling p/c states in the bios and that seemed to help one of the red bars in LatencyMon but the other was still red. So like I said I looked around and found that article. I just downloaded the batch files(towards bottom of page) he had for disabling and enabling power throttling. Ran the disable one, rebooted, and boom back to butter smooth gaming and everything else!! I really thought something was wrong with a piece of hardware in my system. I jumped into GTA5 and played for about half an hour and didn't get any of the stuttering at all. Every game I tried had none of that crazy stuttering! Surfed around a bit and watched some videos and all is good. Just thought I'd report back on how I fixed it if anyone else seems to have that problem. Thanks for the replies and info. Oh the article is this...

    Cool finding. Please, write about it in this thread https://forums.guru3d.com/threads/windows-10-tips-and-tweaks.401262/

    PS I disabled power throttling through registry, but as before that only one (fake) process shows enabled power throtttling - System interrupts

    disable it at the global policy level and reboot,
    otherwise set windows to Performance power profile, on balanced and low performance power throttling is used.

    Strange thing is today System interrupts shows disabled power throttling... I wanted to see the impact of switching from my default balanced plan to performance one, I launched Task Manager and found out...

    I checked last night when I read his report, my task manager had disabled for all processes, and I changed to power saver and balanced and it still showed all disabled.
    I even looked at power management in reg and I couldn't find anything, but I might of missed it if it is worded oddly.

    Anyway, I enabled it in GPE just for kicks.

    Edit; system interrupts is marked enabled.
    Edit2: I see now this is only supported on newer CPU's Broadwell/Skylake, also if you enable it through GPE and then remove it, it will still be enabled cause the setting is not in policy area but in the reg key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerThrottling, PowerThrottlingOff DWORD 1

    Yeh, I checked this last night and thought they were all disabled, this morning I have system interrupt showing enabled. That is with GPE enabled to disable power throttling.

    I guess whole power throttling is relevant only to mobile rigs.

    Where do you see this?

    Then I should not see it "Enabled" on my rig with IB-E CPU.

    PS Mentioned article was published APRIL 18, 2017, and said "Note: Power Throttling is currently available only for processors with Intel’s Speed Shift technology, available in Intel’s 6th-gen (and beyond) Core processors – we’re working on expanding support to other processors as well over the next few months."

    You might see it enabled because they also wrote
    "we’re working on expanding support to other processors as well over the next few months."

    but tbh i didn't think the onchip power manager was implemented till haswell-e

    I am on 3570k and I get same results in TM with it enabled or disabled, only process with enabled is system interrupt.
    My feeling this is more for mobile platforms.
    Probably also similar to the low latency speed-step they introduced in Skylake.

    Well I'm back over here cause it seems I still have malfunctions.... Here is my LatnecyMon report. Is there something in it that shows a prob?

    Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
    LatencyMon has been analyzing your system for 0:30:04 (h:mm:ss) on all processors.

    CPU SPEED
    _________________________________________________________________________________________________________
    Reported CPU speed: 4092 MHz

    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): 932.70
    Average measured interrupt to process latency (µs): 3.421270

    Highest measured interrupt to DPC latency (µs): 930.40
    Average measured interrupt to DPC latency (µs): 1.472448


    _________________________________________________________________________________________________________
    REPORTED ISRs
    _________________________________________________________________________________________________________
    Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

    Highest ISR routine execution time (µs): 227.403715
    Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

    Highest reported total ISR routine time (%): 0.043594

    _________________________________________________________________________________________________________
    REPORTED DPCs
    _________________________________________________________________________________________________________
    DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

    _________________________________________________________________________________________________________
    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: system

    Total number of hard pagefaults 9276
    Hard pagefault count of hardest hit process: 3283
    Number of processes hit: 27
