Hallo liebe Communitiy! Ich bin neu hier und habe gleich mal ein ernstes Problem! :-/
Ich habe mir einen neuen Laptop gekauft um richtig gut, ohne Probleme mit Cubase arbeiten zu können. Dabei benutze ich auch viele Virtuelle Instrumente, wie NI Studio Drumm, Scarabee Bass, Session Horns Pro, einige EastWest Instrumente (Hollywood Strings,…)
Mein Laptop hat folgende Konfiguration:
SCHENKER W704 mobile Workstation 43,9cm (17.3")
. 43,9cm (17.3") Full-HD (1920*1080) Non-Glare
. AMD Radeon R9 M290X 4096MB GDDR5
. Intel Core i7-4910MQ - 2,90 - 3,90GHz 8MB 47W
. 32GB (4x8192) SO-DIMM DDR3 RAM 1600MHz Crucial
. 1000GB SATA-III SSD Samsung 840 EVO Series (MZ-7TE1T0BW)
. 1000GB SATA-III 7200U/Min HGST Travelstar 7K1000 (HTS721010A9E630)
. Blu-ray Brenner (Blu-Ray Lesen- Schreiben / DVD Multinorm) -ohne Softw.
. Intel Wireless-AC 3160 (inkl. Bluetooth)
. Microsoft Windows 8.1 Pro 64 Bit
. Cubase Artist 7.5
Das Problem:
Trotz des eingeltich doch recht üppigen Prozessors, SSD Platte und des großen Arbeitsspeichers kommt es auch schon bei kleineren Projekten zu Leistungsspitzen, die zu Ruckeln und Knacksern führen (mein alter PC konnte das besser ahndeln udn der war deutlich schlechter aufgestellt…)
Ich habe auch bereits Latency Mon und DPC Latency Checker ausgeführt.
Ergebnisse:
Latency Mon:
Der Balken der Highest reported hard pagefault resolution time ist am Anschlag.
Nach Abschluss heißt es: “Your system seems to have difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.”
Unter Drivers kann man sehen, dass “Wdf0 1000.sys” die höchste Execution von 0,274591 ms hat und bei Total Execution steht 21835,184740.
Ist das normal? Habe schon herausgefunden, dass “Wdf0 1000.sys” eine Windows Datei ist und der Schädling wohl eher ein Treiber ist, der ständig darauf zugreift.
Hier noch das “Stats”-Ergebnis:
CONCLUSION
Your system seems to have difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. 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 0:04:43 (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): 1261,375919
Average measured interrupt to process latency (µs): 5,065816
Highest measured interrupt to DPC latency (µs): 1259,606312
Average measured interrupt to DPC latency (µs): 1,237407

\
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.

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: cubase7.5.exe
Total number of hard pagefaults 1041
Hard pagefault count of hardest hit process: 945
Highest hard pagefault resolution time (µs): 84012,435880
Total time spent in hard pagefaults (%): 0,026548
Number of processes hit: 6

DPC Latency Checker:
Zeigt permanent eine Latenz von um die 1 ms an mit einer Spitze von 2,677ms und dem Ergebnis:
“Some device drivers on this machine behave bad and will probably cause drop-outs in real-time audio and/or video streams. To isolate the misbehaving driver use Device Manager and disable/re-enable various devices, one at a time. Try network and W-LAN adapters, modems, internal sound devices, USB host controllers, etc.”
Das ist doch nicht normal für einen Computer der oben genannten Konfiguration, oder?
Ich habe auch schon den Modus für optimale Audioleistung von Steinberg aktiviert.
Übrigens diese Leistungsspitzen treten auch auf, wenn ich gerade nichta uf Play gedrückt habe!
Wäre Euch wirklich enorm für Eure Hilfe dankbar!!!
Viele Grüße!
Tobi
