Someone has posted a guide on the 3d guru forum claiming to have completely stopped all VRR flicker on his OLED.

His "solution" isn't very complicated; use the CRU tool to create to a custom windows resolution for your monitor or TV and set the max refresh rate to 10hz below native for the panel. So if it's a 120hz TV, set the refresh to 110hz.

And that's it, they claim capping the window output refresh to 10hz below the monitor's native max will stop all VRR flickering. However don't be confused with framerate and refresh, capping framerate to 10fps below max refresh does not fix flicker, only capping the refresh will fix the flicker according to the users

 
Someone can try it and report results


Saw this from another post on that forum, guy has a 240hz woled monitors

"Fixed flicker with CRU for Gsync!

Just set 24-229Hz in refresh range and edit 1440p resolution in Display ID data block to 230Hz (double click on it and just edit Hz).
Tested so far Diablo 4 HDR as it has prominent when loading - grey flicker - No More !

Finally fixed permanently, VRR works as it does with IPS !!
Tested in:
BF 2042 HDR no loading screen strobing/flicker
Diablo 4 HDR ^^same ^^
Forza H5 HDR ^^same ^^
Razer Synapse no flicker in Studio Mode (I have Huntsman V2 Linear + Naga Trinity combo)
No flicker in Photoshp also.

UPD.2
Explanation:
The problem is that, the signaling goes beyond safe bounds thus flicker/strobing occurs (My monitor is 240Hz so im assuming that, value 230Hz is safe and in-bounds).
Tweak is about to have much safer Signal Out of bounds margin of 10Hz."
