Question High dpc latency

Yours isn't that bad
GS0Q6mk.jpg

that was mine a few months ago

Nvidia being top is both normal but can also be part of the cause.
see if this helps
  1. open Nvidia control panel
  2. pick Manage 3d Settings
  3. scroll the right panel down to: Power Management Mode
  4. Change it to Prefer Maximum performance
  5. click apply
Some of these might help, I got the Nvidia tip from this video

What are specs of the PC?
