VR HMD I live in real reality and don't need a virtual one.
Software Windows 10 and 11
I recently got fed up with W11 and all that stuff and jumped the gun, ultimately reverting back to W10. That's the build I loaded directly from the M$ and activated using one of a billion OEM-keys I own so it's all safe and sound. We're talking my "DLSS" system if that matters.

However, Desktop Window Manager (dwm.exe) seems to be allergic to 59.94 Hz refresh rate of my monitor. It results in my desktop FPS being rather fractions of one than steady 59.94. Anything UI related is the opposite of butter smooth. Like I'm trying to run Crysis on a PC from 1992. Killing the dwm.exe process temporarily fixes the problem. Reinstalling drivers doesn't do anything. DDU was also tried to no avail.

And when I overclocked my display to 60 Hz the issue has gone. I reverted back to 59.94: it's come back. Not like it's a big deal because I can't tell the difference between 59.94 and 60, and 60 is better anyway.

But WHY!? It has never happened to me before.
