Schenker DTR15 and DPC latency for DAW use

Hi,

I got a fairly recent DTR15 from Schenker/MYSN and really love it.

However, there seems to be a problem with the DPC latency, which makes it difficult to use this laptop for music production.

On my previous laptop (Schenker H506) I had no problems with the DPC latency, and I was able to run my audio card (RME Fireface) in 48 sample buffer mode.

With the DTR15, I can barely use 1024 sample buffer, let alone anything smaller.

The biggest cause for DPC latency seems to be APCI.sys. Which is kind of unfortunate, as it probably means that there isn't much that can be done. Here's a screenshot from LatencyMon:

(embedding seems to be broken...)

Anybody with the same problems?

The rig I got is:
i7 8700k
64gb RAM
EVO 960 Pro
GTX 1070

Best regards,
Sampsa

 

ACPI.sys is tricky to figure out.

You can take a crack at this: https://www.sweetwater.com/sweetcare/articles/pc-optimization-guide-for-windows-10/

From what I've read, there's no clear cut answer to the ACPI issue, and it's more prevalent on laptops. Good luck!

 

FYI I have reached out to @snlehton on pm to ask some questions so that we can compare with our internal tests and offer some suggestions. Once an improvement in the performance has been confirmed, I will be able to update the thread here with definitive information

 

bump... any updates on the dpc latency issue ?

 

P7 systems can handle around 200-300 ms DPC

ACPI Spikes:
- Remove Clevo Control Center

Other DPC causes:
NVIDIA - Switching Power modes can cause DPC, when using it live just disable NVIDIA in the Device Manager or Lock the Power State (plenty of software for that)
WIFI/LAN - Should not be much, but if you need critical low DPC just turn Airplane mode ON

This is what you should get:


And that´s with Fan Control Software, WIFI/LAN on and a variety of other stuff.
