_________________________________________________________________________________________________________ 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 or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. 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 0:36:57 (h:mm:ss) on all processors. _________________________________________________________________________________________________________ SYSTEM INFORMATION _________________________________________________________________________________________________________ Computer name: DESKTOPPC OS version: Windows 11, 10.0, version 2009, build: 22000 (x64) Hardware: To Be Filled By O.E.M., To Be Filled By O.E.M.

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): 383,20 Average measured interrupt to process latency (µs): 15,614586 Highest measured interrupt to DPC latency (µs): 376,90 Average measured interrupt to DPC latency (µs): 11,378891 _________________________________________________________________________________________________________ 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): 3459,907598 Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation Highest reported total ISR routine time (%): 0,163589 Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation Total time spent in ISRs (%) 0,171217 ISR count (execution time <250 µs): 2027538 ISR count (execution time 250-500 µs): 0 ISR count (execution time 500-1000 µs): 185 ISR count (execution time 1000-2000 µs): 0 ISR count (execution time 2000-4000 µs): 1 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.

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.
