Windows 10: V1903 Causing DPC Latency Hits

I use my desktop for general PC ops and also for my recording studio. With all versions including 1809 I haven't had any issues with latency/clicks/dropouts in audio, etc. Resplendence Latency Mon shows no problems. However, with 1903 there is Latency problems. The "culprits" according to Latency Mon are USB bus and/or High Definition Audio (Realtek). I've restored my PC back to the 1809 5/22/19 disc image I did before upgrading to 1903. I've run Latency Mon again after restoring and still no issues (with 1809). This has also been reported on the gearslutz forum by another user.
Here are the Latency Mon screenshots, both for 1903 and 1809.

Terrible DPC Latency


DPC latency problems are usually caused by bum drivers. The DPC latency checker should give you a hint where to look (if you have a lot of red bars).

 

High DPC latency

I use my Dell XPS for recording and live playback but the system suffers from high DPC latency caused by ACPI driver.

I removed Dell audio drivers and installed those from RealTek with no avail. Latency is an issue because I need this computer for live recording. Please your advice.
