    Stuttering/microfreezing in games and demanding tasks. DPC latency issues.

    Hey everyone!




    I've been having this very weird problem since close to 2 years, basically what's happening is my mouse and display freeze for a very short amount of time every few seconds while gaming/performing resource demanding tasks on my PC.


    There's some very occasional audio crackling/popping when it happens, here's an example I recorded while playing CS:GO: afadasdasdas - YouTube


    Games such as CS:GO tend to be very unsmooth and jittery even though I usually get 200-400 FPS and I own a 144Hz monitor.

    The funniest part is that it even happens in Windows quite often, for example I've noticed it sometimes happens while opening the start menu, launching a program or even when checking for Windows updates.




    I've attempted fixing this issue for a pretty long time and nothing seemed to help.

    Here's the list of tweaks I've tried already:

    - Reinstalling Windows (15+ times, tried both Windows 7 and 10)

    - BIOS tweaks (disabling HPET, EIST, C-States etc.)

    - Made sure every single driver is up to date

    - GPU tweaks (disabling shader cache/setting texture filtering to high performance mode)

    - Most Windows registry tweaks (network throttling/assigning games a higher priority) so far from my experience they usually only make things worse

    - Putting drivers in MSI mode




    I've also measured my DPC latency and interrupts using Latencymon, here are the results:

    - Drivers Tab: Imgur: The most awesome images on the Internet




    My PC specs:

    - Intel Core i5-6500 @3.20 GHz
    - Asus Radeon R9 380X 4GB
    - Corsair Vengeance LPX, DDR4, 2x4GB, 2133MHz
    - MSI B150M Mortar
    - Western Digital Caviar Blue, 3.5'', 1TB
    - GoodRam CX300, 2.5", 240GB
    - Corsair VS Series 550W



    Any help is greatly appreciated, thanks in advance!

    Here's another video representing the issue: Mouse issues/PC microfreezes - YouTube

    I've also tested a different GPU and RAM sticks, booted the PC with only my SSD connected and unfortunately the problem is still there.

    Any ideas?
