Problemas con alta DPC Latency. Windows 10 y Cubase 10 Elements

Un cordial saludo comunidad.
Recientemente me he registrado en este portal, aunque tenía meses leyendo información espectacular.

Acudo al foro a ver si alguno de vosotros ha sufrido o sufre lo que yo en este momento.
Me estoy instalando mi home studio para comenzar con la producción musical, y la informática no me lo permite.

Tengo una desmesurada y brutal latencia que me impide cualquier proceso en Cubase 10. Tengo un laptop HP, i7 8th Gen, 8 GB RAM, 1 TB Disco Duro, Windows 10 version 1803, con una interface Focusrite Scarlet 2i2.

He seguido todas las configuraciones recomendadas por Steingerg, Focusrite, Windows y un montón de foros del mundo entero y sigo sin solucionar.

Después de gastarme una importante cantidad de dinero (por lo menos para mi), aún no puedo grabar la primera línea de bajo ni programar ninguna secuencia.

Estoy desesperado porque le he dedicado más de 30 horas a buscar la solución y ha sido imposible.

¿Alguno de vosotros ha tenido esta mala experiencia?

¿Sabéis de algún tipo de solución?


Salud, y que la música no pare nunca,
Luis.

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. 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 0:02:11  (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):   4121,699633

Average measured interrupt to process latency (µs):   2,835025


Highest measured interrupt to DPC latency (µs):       4117,073131

Average measured interrupt to DPC latency (µs):       1,116231



_________________________________________________________________________________________________________

 REPORTED ISRs

_________________________________________________________________________________________________________

Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Total time spent in ISRs (%)                          0,059313


ISR count (execution time <250 µs):                   32358

ISR count (execution time 250-500 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):              4122,288655

Driver with highest DPC routine execution time:       Wdf01000.sys - Motor en tiempo de ejecución del marco de controlador en modo kernel, Microsoft Corporation


Highest reported total DPC routine time (%):          0,111907

Driver with highest DPC total execution time:         Wdf01000.sys - Motor en tiempo de ejecución del marco de controlador en modo kernel, Microsoft Corporation


Total time spent in DPCs (%)                          0,160415


DPC count (execution time <250 µs):                   341949

DPC count (execution time 250-500 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:                 dpclat.exe


Total number of hard pagefaults                       220

Hard pagefault count of hardest hit process:          76

Number of processes hit:                              17

Prueba con este programa para ver si hay controladores que deban ser actualizados:

Wdf01000.sys no es algo que debas desactivar, es un proceso responsable de la interconexión con dispositivos.

La verdad es que el equipo no es ideal, los procesadores "U" como el tuyo son de bajo consumo y tener un SSD también se gradece, aunque sea uno pequeño para software.

Prueba a deshabilitar en BIOS las controladoras de audio integrado y red, selecciona el modo de alto rendimiento en el panel de control si no lo has hecho ya. Si puedes deshabilitar otros dispositivos como lector de tarjetas o bluetooth, prueba también, a ver como queda la cosa. Para un vistazo a la latencia puedes usar el DPC Latency Checker.

PD: Si el equipo trae tarjeta de vídeo dedicada e integrada igual puedes deshabilitar una. Puedes incluso deshabilitar de uno en uno, incluso desde Windows, con ojos puestos en el DPC a ver si ganas algo.

Lo que dice Obione es un buen punto de inicio, yo cuando pincho con el pc y la controladora desactivo además wifi, antivirus y ejecuto un fichero .reg el cual me para un montón de servicios de windows que no voy a necesitar.

Igualmente, donde mas noté el cambio con mi problema de latencia fue al usar el driver Asio de mi controladora, este era el culpable. Sorprendentemente utilizando el nativo de windows que se configura automáticamente me funciona muchísimo mejor...
