_________________________________________________________________________________________________________ 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 0:06:06 (h:mm:ss) on all processors. _________________________________________________________________________________________________________ SYSTEM INFORMATION _________________________________________________________________________________________________________ Computer name: DESKTOP-P3QVVVA OS version: Windows 10 , 10.0, version 1903, build: 18362 (x64) Hardware: ASUSTeK COMPUTER INC., PRIME X470-PRO CPU: AuthenticAMD AMD Ryzen 7 2700X Eight-Core Processor Logical processors: 16 Processor groups: 1 RAM: 16300 MB total _________________________________________________________________________________________________________ CPU SPEED _________________________________________________________________________________________________________ Reported CPU speed: 3693 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): 2828,20 Average measured interrupt to process latency (µs): 5,303885 Highest measured interrupt to DPC latency (µs): 2822,80 Average measured interrupt to DPC latency (µs): 2,246669 _________________________________________________________________________________________________________ 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): 329,613593 Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation Highest reported total ISR routine time (%): 0,109902 Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation Total time spent in ISRs (%) 0,114547 ISR count (execution time <250 µs): 437785 ISR count (execution time 250-500 µs): 0 ISR count (execution time 500-999 µs): 1 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): 433,850799 Driver with highest DPC routine execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 431.60 , NVIDIA Corporation Highest reported total DPC routine time (%): 0,053187 Driver with highest DPC total execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation Total time spent in DPCs (%) 0,170895 DPC count (execution time <250 µs): 1495721 DPC count (execution time 250-500 µs): 0 DPC count (execution time 500-999 µs): 22 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: bfv.exe Total number of hard pagefaults 13768 Hard pagefault count of hardest hit process: 10182 Number of processes hit: 38
