VST Performance peaks and spikes

Post by aleksaks123 »

I dont know what to do anymore. I am starting to feel a lot of depression because I cant fix this. I have 9.5 updated cubase version. Everything is licensed. I also have a bought Windows 10 Pro 64 bit (that has been updated to the last file). All of my drivers on my laptop are updated. And still I am getting spikes and peaks in the VST performance meter.

I have a HP Omen lap top with the following specifications:

Operating System

CPU
Intel Core i7 7700HQ @ 2.80GHz 47 °C

Storage

DTSOFT Virtual CdRom Device
.............
Audio

The peaks are also developing when I am not even playing audio just in the open project.
Even sometimes if I load a Waves 88 piano and play some chords, after a while I will get a peak.

I also did tests with Latencymon and these are the results:

CONCLUSION
_________________________________________________________________________________________________________
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC 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 0:01:07 (h:mm:ss) on all processors.

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): 1074.324982
Average measured interrupt to process latency (µs): 5.662990

Highest measured interrupt to DPC latency (µs): 1014.154031
Average measured interrupt to DPC latency (µs): 1.959643


_________________________________________________________________________________________________________
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): 205.015670
Driver with highest ISR routine execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

Highest reported total ISR routine time (%): 0.023822
Driver with highest ISR total time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

Total time spent in ISRs (%) 0.045241

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): 1262.219017
Driver with highest DPC routine execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

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: fontdrvhost.exe

Total number of hard pagefaults 13
Hard pagefault count of hardest hit process: 7
Number of processes hit: 4

This is even happening if i put the sample rate to 1024 or 2048. Still everything is bad...

Not its only happening when i click to record something. It is not happening when i am just playing. And the same moment i press on a channel to record a midi track with omnisphere or anything its getting peaks and crackles. The same moment i deselect the channel everything is back to normal.

Solved: I have cubase 9.5, win10-64, I7-9700k (9th) 16 Gb Ram, Audient ID22, Nvidia GTX750. Used to have same problem with a lot of peaks and drop-outs.
My settings: VST Audio System
32 bit float Processing
actvate MultiProcessing - yes
activate asio-Guard-yes
Asio Guard level - normal
Activate Steinberg Audio Power scheme - yes (very important)
...and that is - no more peaks
hope it works for you guys.
