This was the first obvious solution I tried.
May or may not be MPO-related (effectively makes some windowed apps act more like exclusive fullscreen when focused):panicaz wrote: ↑30 Nov 2022, 09:40This was the first obvious solution I tried.
Today I installed old Windows 10 1909 on a separate SSD and G-sync works totally fine. No VRR trigger in windowed mode if disabled in NVCP. So the problem is most likely in Windows 10 updates somwere between 1909 and 22H2 version.
Any thoughts about fixing it on modern version of Windows 10?
Read about this about a week ago, though didn't consider this one as a valid solution -- did this change per those versions?

Nvidia offers a regedit to disable MPO:

You can attempt the regedit on your original drive (containing the newer version of Windows) to see whether that resolves your particular issue.
MPO support for Nvidia GPUs was introduced in driver version 461.09. I don't know what Windows 10 version introduced it at the OS-level off-the-top-of-my-head though.
Yep! This works. Disabling MPO fixes stuttering and flickering with G-SYNC enabled.jorimt wrote: ↑30 Nov 2022, 10:14May or may not be MPO-related (effectively makes some windowed apps act more like exclusive fullscreen when focused):
