Question High Interrupts / DPC Lantency

May 9, 2019
Does anybody know how to solve this?
I did a lot of research and I couldn't find a fix.
I'm having FPS drops in some games, random mouse and sound stutter.

My specs:
CPU: AMD Ryzen 7 2700 @ 4,1GHz with Liquid Cooler
GPU: MSI RTX 2080 Ventus 8GB OC
Memory: 2x8GB G.Skill Trident Z RGB 3.2GHz
Motherboard: MSI B450 Tomahawk
Storage: Intel SSD 760p NVMe 512GB
PSU: Corsair TX 750M
OS: Windows 10 1903

  • All drivers are up to date;
  • Fresh installed Windows;
  • I tried to disable the ethernet card, internal audio card, serial port and a lot of devices on Device Manager;
  • I tried a different Mobo, PSU and RAMs;
  • I tried to change some drivers from IRQ to MSI mode.
Nothing seems to improve the latency.
Please help!
