Hi
Hope someone can help me here but I seem to be experiencing extremely high latency which is affecting me using this Laptop for DJ use.
I use 2 programs for digital DJing. Native Instruments Traktor (Timecoded Vinyls) and Pioneer's Rekordbox (Pioneer Controller).
I bought this laptop just over a year ago from Curry's PC World and to be honest the first few months was ok but then I started to experience audio drop outs back then.
I used to get away with solving the problem with reinstalling windows 10 and everything would go back to normal.
However, I'd started getting problems yet again with latency recently. Thought I'd format and try again and this time it's not worked This time it's unbearable.
With Rekordbox I'd get stuttering and crackling when sometimes loading songs into the play zone on the program when using a controller. With Traktor, again I get stuttering and crackling and also playback issues. Just like here
http://www.youtube.com/watch?v=ZyjdEq_33l8 .
As you can see with the issues I get with Traktor is while the track is playing on the timecoded vinyl, the pitch will bend on its own, as if you sped up the vinyl to catch up the beat matching, but it'll do it on it's own and will do it even when both records are playing simultaneously. Both decks together will pitch bend.
So I decided to format the computer yet again but this time I stripped it right back as if I was going to sell on the computer. Everything taken off.
After 4 hours of waiting I tried again.
Nothing has been touched with the laptop, just Latencymon installed so I can see if anything happens.
whilst leaving Latencymon on for a while I get the biggest spike I've ever seen with a file called ACPI.sys spiking at 55ms and that's from a brand new fresh install. Even Wdf01000.sys and dxgkml.sys are also reporting issues.
Has anyone any ideas how I can solve this issue please. The laptop wasn't cheap as it's a (basic) gaming laptop and I thought having a gaming laptop there'd be no issues at all.
Hope someone can help.
Thank you
Below is the report from Latencymon

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 0:41:07 (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): 46151.40
Average measured interrupt to process latency (µs): 7.149183
Highest measured interrupt to DPC latency (µs): 46146.50
Average measured interrupt to DPC latency (µs): 2.482851

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.

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

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: msmpeng.exe
Total number of hard pagefaults 9592
Hard pagefault count of hardest hit process: 3299
Number of processes hit: 88
