    Hello everybody, I'd like to ask for help on finding the cause of mouse delay and short stutters in games, because for fps games accurate and fast mouse movements are the biggest advantage over enemies.

    I've done clean windows 10 install yesterday (formatted both SSD and HDD). Haven't installed a single program besides steam and 2 games. Windows update installed everything it needs. Haven't installed any drivers from motherboard manually and I can really say that Microsoft drivers made significant improvement on how the mouse behaves in game such as cs go, over the ones from asrock. However, Im not sure if my pc is optimized for best performance without the custom drivers made specially for my motherboard.

    My computer ->
    CPU: Intel i5 4690
    GPU: GTX 1060 3gb
    RAM: DDR3 Kingston HyperX blue 2x4 1333mhz cl9
    MOBO: ASROCK H97M Pro 4
    HDD: WD BLUE 3.5 1TB 7200RPM
    SSD: Corsair Force LS 60GB
    PSU: Cooler Master Thunder M 620w
    CPU Cooler: Cooler Master Hyper evo 212
    Mouse: Logitech g402
    Monitor: Dell p2314h 1920x1080@60hz

    Both processor and video card do not reach over 45 Celsius while gaming.

    Things done to solve the problem:
    1. Disabled xbox dvr
    2. Switched between balanced - performance mode in battery settings.
    3. Newest NVidia drivers
    4. Ran latency mon test: http://imgur.com/a/033yx

    Summary
    _________________________________________________________________________________________________________
    CONCLUSION
    _________________________________________________________________________________________________________
    Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
    LatencyMon has been analyzing your system for 0:17:34 (h:mm:ss) on all processors.

    SYSTEM INFORMATION
    _________________________________________________________________________________________________________
    Computer name: DESKTOP-BNDSOFC
    OS version: Windows 10 , 10.0, build: 14393 (x64)
    Hardware: ASRock, H97M Pro4
    CPU: GenuineIntel Intel(R) Core(TM) i5-4690 CPU @ 3.50GHz
    Logical processors: 4
    Processor groups: 1
    RAM: 8127 MB total


    _________________________________________________________________________________________________________
    CPU SPEED
    _________________________________________________________________________________________________________
    Reported CPU speed: 3499 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): 936,791864
    Average measured interrupt to process latency (µs): 2,623720

    Highest measured interrupt to DPC latency (µs): 916,59860
    Average measured interrupt to DPC latency (µs): 0,917977


    _________________________________________________________________________________________________________
    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): 196,412975
    Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

    Highest reported total ISR routine time (%): 0,179504
    Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

    Total time spent in ISRs (%) 0,223668

    ISR count (execution time <250 µs): 1150640
    ISR count (execution time 250-500 µs): 0
    ISR count (execution time 500-999 µs): 0
    ISR count (execution time 1000-1999 µs): 0
    ISR count (execution time 2000-3999 µs): 0
    ISR count (execution time >=4000 µs): 0


    _________________________________________________________________________________________________________
    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.

    Highest DPC routine execution time (µs): 867,317805
    Driver with highest DPC routine execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation

    Highest reported total DPC routine time (%): 0,073889
    Driver with highest DPC total execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

    Total time spent in DPCs (%) 0,307659

    DPC count (execution time <250 µs): 3990422
    DPC count (execution time 250-500 µs): 0
    DPC count (execution time 500-999 µs): 37
    DPC count (execution time 1000-1999 µs): 0
    DPC count (execution time 2000-3999 µs): 0
    DPC count (execution time >=4000 µs): 0


    _________________________________________________________________________________________________________
    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: svchost.exe

    Total number of hard pagefaults 9640
    Hard pagefault count of hardest hit process: 2392
    Highest hard pagefault resolution time (µs): 196781,727922
    Total time spent in hard pagefaults (%): 0,247774
    Number of processes hit: 32

    Sorry for making several threads, the few others were really messy.
