I'm a Windows 11 user, since the most recent update, along with Nvidia's new update that released June 15th, I've been experiencing severe latency and lag- especially whilst in online games. Also keyboard stuttering, I've reset and reverted to regular Windows version to no avail. Updated all drivers possible. Reverted ones of concern.
Below is info from LatencyMon;

Conclusion: Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

Thank you for the reply!
I've done so and haven't seen changes yet. I'll check the video though.

Slightly lower reading, but awful keyboard stuttering

So you on the rtm version?
Did you post about the problem on the insiders forum as things like this are why Insiders exists, so problems can be identified before release.

Its likely others have same problem.
which build of win 11

  1. right click start
  2. choose run...
  3. type winver and press enter
  4. My current build is 22000.739 but I know Insiders is different?

Hey sir, we've got the same version code. I've reinstalled Windows again and slowly updated all its drivers - although the issue persists, I did post to insiders forum with no relatable cases.

Issue has gotten more difficult to navigate through Windows. Gaming and productivity nearly impossible

ntoskrnl = windows kernel. Its unlikely to be cause, though it often gets blamed for errors. Mainly as its involved in almost every operation of the PC. Its probably a driver to blame.

what are specs of the PC?
latest chipset drivers?
