Just received a brand new Dell XPS 7590 i7-9750 and it has latency issues.

acpi.sys is peaking at 2300ms.

What a time to be alive.

Just got a new XPS 15 7590 for the purposes of music production.

Even after installing a clean boot of Windows, DPC latency is spiking into the 1600 range.

This is unusable for audio production, and could actually deafen people on a large audio system if you were dumb enough to hook it up to one.

One of many fails by Dell i have experienced in the last few weeks

Any info on the fans cycling issues that occurred in the previous models. Interested to see if you do low level tasks like opening a browser if the fans spin up and down in a cycling way

The Disconnected Modern Standby can be disabled via registry change and you'll get S3 standby back. That was what I did with my Inspiron 15 7590

Dell throttles at 75ish C across the line, especially in the systems with a dGPU since nvidia's limit for the GP108/107 happens to be 74C

Thank you, Notebookcheck, for the update. I've been wanting to buy an xps 15. Your reviews are always thorough and I base a lot of my decisions on whether to buy a laptop off them. At this stage it looks like the new xps simply has too many of the old problems to be worth the plunge. Modern Windows laptops and the shortcomings of both them and Windows 10 have me leaning firmly towards buying Apple - I don't think Dell, Lenovo, HP.. etc, either realize this or care.

I wouldn't call DPC latency fixed with spikes upto 800us. Ideally it would sit under 400. Also I expect if the test was run for longer than 2 minutes we'd still see higher spikes.

Dell has done a great job in improving DPC latency but there is still further work to be done before anyone should can call it fixed .

The XPS 15 7590 is less than two weeks old, but consumers are already realising that the device retains some of the issues that plagued its predecessors. 75 °C throttling and no S3 sleep sound familiar to anyone? At least Dell appears to have resolved DPC latency issues with the new XPS 15 though.
