XPS 15 7590, DPC Latency issues, DAW usage

I can't answer specifically about this model.  However, I have a recording studio, using Cakewalk Sonar and Studio One 4.5 Pro.  

One issue that commonly comes up on recording forums about latency is NVIDIA video.  That seems to be a common issue.  I have an Inspiron 15 gaming laptop that can use either the Intel CPU video or the NVIDIA video.  If I use Intel Resplendence Latency Mon program does not show any problems.  If I use the NVIDIA it does.  I field tested a Dell G7 gaming laptop back in January of this year and the same thing showed up - use Intel video and its OK for audio DAW production but use NVIDIA and there are Latency issues and dropouts.

However, even using Intel video with the Dell factory image and system "tweaking" I was still experiencing a dropout every 2 to 3 minutes.  My Inspiron 15 came with an M.2 SSD and space to install either a laptop hard drive or a full size SSD.  I had a spare full size SSD so I installed that and created a Win 10 Dual Boot system, one with the full Dell disc image and a second with a minimum Win 10 installation (only needed drivers).  I installed Cakewalk Sonar and Studio One 4.5 Pro on the new Win 10 installation.  Resplendence Latency Mon can run for hours and no problems.   Thus, If I want to use the PC for regular PC applications or gaming I boot to the Dell Win 10 installation; if I want to use it as a DAW I boot to the separate "Recording" Win 10 install.

One additional comment. The Intel CPU video is fine for DAW work, you don't need the NVIDIA (or AMD) video.

Thank you very much for your suggestions! I will consider setting up a dual boot system at some point, but first ( once the machine arrives), I'm going to try how things work out with or without NVIDIA. I'm not gaming much, but certain tasks I'd like to do down the line will require some GPU power.

However on a similar note, here JoshCumbee suggests:

"Also, I assigned the Intel graphics to run my system and dGPU to run my DAW."

What do you think of that approach?

Thank you!

Those only apply to that person.  e.g. "MaxxAudio" is not on all PC's.  The buffer size is recording interface unit hardware/driver dependent.  I can run my MOTU 4pre buffer at 64 reliably and low latency.  I had a Presonus unit and 512 buffer was the best I could do reliably with that unit.  I had a Roland Octa-Capture and 128 buffer was the best I could do.

Intel video is more than adequate for DAW work.  NVIDA is for video intensive items.

Thus I don't agree with that user for "all" DAW PC's.  

The opinions of audio folks are mixed. So if you had asked before ordering, I'd suggest you to look for laptop choice suggestions at Gearslutz or such. I recall the opinion was that there was something beyond the "ordinary" NVidia driver issues wrong with Dell laptops. During the half-a-year saga of fixing this for the 9570, certain design compromises were mentioned. 

But since you've already ordered, I suggest you to just wait and see how it works for you, and report back of course. Learn how to test using LatencyMon and for missing samples. In case of trouble, try the general suggestions, like clean install, disabling eGPU, turning off CPU C states and hyperthreading, etc. So that you can decide before you run out of the return window. Don't count on support to help you in time.

I have a desktop for my primary DAW system.  There are no tweaks except power plan is set to High Performance.

As previously noted a "clean install" with minimum drivers and nothing else was my "fix" to use my Inspiron 15 "gaming" laptop for DAW work.  Also, as previously noted the field testing on a Dell G7 gaming laptop, disabling NVIDIA fixed its audio dropout and Latency Mon issues.  I installed Bandlab Cakewalk (Sonar) on the G7 and did a three hour "live" band recording (used an MOTU 896Mk3 Hybrid recording interface unit) and there were no dropouts or any other recording issue.  I did disable the NIC (and wireless) during recording.

I'm on the gearslutz forum and there was a recent (about a month or so ago) that there was general agreement on not using NVIDIA as it caused recording problems (and Resplendence Latency Mon).  Also on the old Sonar forum (before Bandlab purchased it) I recall several threads about NVIDIA issues.

Sure NVidia is a known latency offender. But with the 9570, bad spikes from acpi.sys were originally reported with all sorts of stuff beside the eGPU and network disabled. Real-time performance is as good as the worst OS kernel part and device driver. If, for instance, it happens to be caused by the thermal downthrottling scheme, on which this laptop happens to vitally depend and can't be disabled, you're busted  

On battery most laptops throttle back.  My Inspiron 5577 gaming laptop does that.  The G7 (i7 8700) gaming laptop I field tested dropped FPS almost in half on battery.  

Thermal can and usually is an issue on laptops.  They try to make them physically small and as quiet as possible and in doing so it affects performance.

I am currently looking into a Laptop for my DAW work and music prod. I am wondering if there are any updates? How did you end up liking the XPS and are these latency issues a real pain or what?
