Highest reported total ISR routine time (%): 0.000439ĭriver with highest ISR total time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft CorporationĭPC 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 ISR routine execution time (µs): 180.708901ĭriver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal. Highest measured interrupt to DPC latency (µs): 2126.10Īverage measured interrupt to DPC latency (µs): 2.732665 ![]() Highest measured interrupt to process latency (µs): 2143.30Īverage measured interrupt to process latency (µs): 8.958971 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. 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. MEASURED INTERRUPT TO USER PROCESS LATENCIES Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results. Note: reported execution times may be calculated based on a fixed reported CPU speed. Hardware: HP ENVY 17 Notebook PC, Hewlett-PackardĬPU: GenuineIntel Intel(R) Core(TM) i7-4710MQ CPU 2.50GHz LatencyMon has been analyzing your system for 0:21:22 (h:mm:ss) on all processors. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. In case you are using a WLAN adapter, try disabling it to get better results. At least one detected problem appears to be network related. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. Your system appears to be having trouble handling real-time audio and other tasks. My PC is an HP Envy 17 j177nr with 16 GB ram.ĭoes anybody know how I can remedy this so I can stream againĮdit: Output of LatencyMon while trying to stream:Ĭode: _ I checked the event viewer but I did not see anything out of the ordinary other than the forced shut off attempt I am using the latest version of OBS Studio and I already ran sfc /scannow and check disk and both pass with flying colors. I already asked the guys over at OBS support and all that they could tell me is that while OBS can trigger these system freezes, the system freeze itself is outside OBS, thus they cannot provide any help in resolving the issue. I used to be able to stream Final Fantasy XIV which is a fairly resource intensive game without issues and only utilizing 20% CPU. Now I cannot even throw on an SNES emulator and stream that without System Interrupts spiking to 100% CPU and freezing my PC. This includes resource heavy games like Need for Speed: Heat. I can game with no issues as long as I am NOT streaming them. The only thing that I have not updated are my Nvidia drivers but I am 100% sure that it is not the fault of the Nvidia drivers as it is the same version of Nvidia drivers when I was streaming with no issues in January. I still get System Interrupts spiking to 100% CPU followed by a system freeze just a couple minutes into the stream. So, I tried installing literally every driver that was listed in Windows Update yet the problem persists. I have NOT made any changes to my PC since OBS was working even for six hour streams other than the normal Windows updates.Ī bit of Googling around suggests that it is almost always a driver problem. ![]() The only way I can unfreeze my system is by holding the power button to force shut off my PC. ![]() Problem is, about two minutes into the stream, a process named "System Interrupts" starts using 100% CPU and about another 30 seconds, my entire system freezes. However, now I am unable to stream on the very same PC that I used to be able to. Before then, I could stream to Facebook Gaming to my heart's content.
