XPS 15 7590 DPC latency

I have read online that the Dell XPS 15 7590 i7-9750H suffers of DSP latency. Are these issues now resolved?

I have read that you could for instance upgrade the BIOS. thank you!

That is funny timing, I had my first really good Serato Lite mix last night.  XPS 15 spazzed  several times over an hour or so.  If I was recording it would be wrecked, so I started looking again.

I found this recent article, and they list XPS 13 as one of the best laptops for digital dj.


I don't know what to make of that.  Just passing it on. 

I noticed in the hardware audio settings of Audition, using UR22 / Yamaha ASIO, the buffer setting only has one choice 512ms.  On Macbook Pro, using same UR22 with "Core Audio" (instead of ASIO on windows?) the buffer setting has a lot more choices, lower and higher, can go up to 2000ms + so I chose the 2000ms.   I don't totally understand what is determining the available buffer choices, the hardware driver or the OS?  (why would SteinbergYamaha have different buffer on mac than PC)? 

I have not had any problems recording on old Macbook like this.  I don't monitor my recordings through the interface so I don't care if there is latency as long as the final result is intact.

I can't tear down my XPS 15 it is too nice for everything non-audio, so I'm still thinking I need a cheaper max air i5 like the article mentions.  To be a dedicated Serato host.

All my software is legit

A lower buffer size relates to lower latency.  I can run my MOTU 4pre at 64 samples reliably and no dropouts in Windows 10 and that results in 2.8 ms recording latency as reported by Cakewalk (Sonar).  

One major issue is the vendor driver, a poorly written driver and there can be problems, including latency and dropouts at low buffer sample rates.  A well written driver and works great.

You won't be able to see my latency graphic until the forum moderator approves it so probably tomorrow it will be visible.

Hi @fireberd ,

Thanks for your reply - you're quite right, however the buffer size actually was quite reasonable, I think 256 samples, certainly no less than that (at least with DJing, you don't need ultra-precision with MIDI data unless you're scratching).  It's a Roland device, so I'd like to assume their drivers should be okay! I did use a different MIDI controller with the XPS 15 and had the same issue, so I don't think it was likely a faulty ASIO driver - this was all prior to me doing the clean install.

I also had tried the Roland controller with my desktop PC, which has a 1st gen Ryzen 5 CPU, and I couldn't replicate the buffering that I originally had on the XPS laptop. I actually use a Focusrite 18i8 USB interface with my Ryzen desktop, I'm able to get down to 96 samples quite comfortably using VST plugins and virtual instruments.  

My Latencymon testing has shown warnings both before and after I did my Windows reinstall, but I'm comforted given it's not actually translating to real-world performance issues with my laptop.  Before my reinstall, I was also testing Serato DJ without using an external audio interface (i.e. just using the Windows Audio drivers), and it didn't cause performance issues - however Latencymon still showed the warnings I've had throughout this experience.

I'm not keen to declare anything being proof-positive at this point, but I think I've reasonably (if not seemingly) narrowed it down to a relationship with the Dell software being installed/active on the laptop, and audio interfaces being connected via USB.  I'll be keen to keep testing though.

Hi @hardware408 

To be honest I literally had zero issues with my XPS 15 running Serato DJ with a number of different controllers, and I was using it regularly between mid 2018 to late 2019.  On paper, it's had a better track record than my 2012 Macbook Pro Retina - because it crashed once on that computer!  

I'm hesitant to call myself an expert, however I'll consider myself a person that's had a better experience with the XPS laptop once the Dell programs have been removed at least - at most combined with a Windows 10 reinstall from scratch.  It might be worth backing everything up and giving it a shot to see if it translates to better results. The Serato-Spazzes you describe sound like what I had before - I'm not getting them anymore.

Regarding the Yamaha interface - Core Audio is Mac's proprietary class compliant audio drivers that hardware manufacturers build their devices against in order for them to work plug-and-play without their own 3rd party drives (I think) - I don't think this technically works with Windows and ASIO, so Yamaha would need to build their own ASIO-compliant drivers in order to get them to work.  It's possible that the Core Audio option offers better options compared to what Yamaha were able to achieve.  It's an older device too (I see it's USB/firewire), so maybe that have something to do with it.
