High latency with Reloop Jockey 3 ME and Traktor scratch pro 2

[netlopez]

Good morning, sorry for my english is very bad.

I have an Intel ® Core ™ 2 Duo with 4 GB of RAM and 64-bit Win7, I followed all instructions from Native Instruments (update drivers, bios, turn off wifi, etc. ..) as I have peak CPU saturation, to try to lower the latency as much as possible but within 23 ms me wrong. I think the driver gives me the USB.SYS saturation (I have only connected the Jockey reloop 3 ME)

I have traktor scratch pro 2

Is there any way to not have these peaks of saturation?

Driver installed --> ASIO Driver V2.9.23 (Win 64)

Firmware installed -->V18

How about your RAM?

[netlopez]

DDR2 de 4 GB

I think I have a good laptop to work at the lowest latency, right?

I'm desperate!!

[Reloop_Dave]

You use Windows so you never ever will have the lowest latency! Windows uses ASIO (google for it), and ASIO always has a higher latency in comparison to CORE Audio (Mac)

[netlopez]

What mac do you recommend?, It's not too expensive.

Please keep in mind that any ASIO driver will cause high CPU load. It's normal by disconnecting the unit that the CPU peaks will lower down.

Maybe you have a try with google and download a programm called LatencyMon. You're able to see which driver is responsible for your peaks.

reloop when I connect, the driver shoots usb.sys

I have only connected via USB reloop and I have updated the chipset of the board but these peak still appear

[Reloop_Dave]

Do you get a Windows bluescreen?

[netlopez]

of course this afternoon I put

[Reloop_Dave]

of course this afternoon I put

Lo siento! But I don´t understand...

[netlopez]

I sorryit is the translator, this afternoon the screenshot attached


Windows bluescreen = Screenshot???

Yes...please...

This is my report:

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 belonging to a driver running in your system appear to be executing for too long.
LatencyMon has been analyzing your system for 0:01:17 (h:mm:ss)
