Hi @raidhy thanks for reaching out. I'm going to try to replicate this issue.
Can you just confirm if the following repro steps/understanding are right:
Is this all the replication steps?
I'm unsure exactly when the problem arises as I don't have custom resolutions, so my refresh rate options go 165, 240, 270Hz. Only the former has functioning VRR, 240Hz also doesn't work from my experience. Other than that, those should be the steps, yes.
Okay, sounds good. I think we have 144hz and 165hz as well. Not sure about the 260hz but I'll give it a shot and get back to you if I have any questions.
Thanks.
Sorry if i wasnt clear. From my testing you won't run into the issue on a 165Hz screen. I think a 240Hz or higher would be necessary. I can try and see if the issue still arises at say 180Hz, but as far as I'm aware VRR functions correctly at 165Hz and you would need a higher refresh rate to test it.
Ah! Okay. That helps narrowing it down. Yeah if you can test it at 180hz let me know. I'll start my hunt for a higher refresh rate monitor.
Hey @raidhy any confirmation on 180Hz? Trying to understand exactly when this issue happens so I can easily replicate it.
Edit:1 and you are connected through display port?
@mujeeb-intel Sorry, life has been in the way recently! I'm not sure of how much use the testing would be though as it would involve creating a custom resolution which may introduce its own issues.
Both displays are connected via displayport.

Description and steps to reproduce [Required]
VRR doesn't seem to be working properly in certain titles at refresh rates higher than 165Hz. I've replicated this behaviour in Baldur's Gate 3 (both DX11 and VK), Forza Horizon 4, and Battlefield 2042. Opening any of these games with any window type at a refresh rate of 270Hz results in a refresh rate that fluctuates seemingly randomly without regard to the in-game framerate. However, setting the refresh rate to 165Hz either in game or in Windows, VRR works as expected. This appears to always happen, regardless of if VRR is set to only fullscreen or fullscreen+windowed. Capping framerate manually or with VSync doesn't change the outcome.
The monitor is G-Sync Compatible and previously worked as intended with my 1660S. Arc Control shows a variable refresh rate range of 48-270Hz. Installing IGCC and turning off Adaptive Sync Plus appears to get VRR working as intended at 270Hz in the above titles, but my desktop is then stuck at 48Hz.
VRR for unsupported games is turned on in Windows. ReBAR and 4G are enabled and this was tested with a clean (DDU) installation of the latest drivers, though I've noted this behaviour on the previous drivers also.
I used Microsoft's Dynamic Refresh Rate Tool for the graphs below, and its output is identical to the values displayed by the monitor's OSD.
Both of these were recorded while in the main menu (~105fps), but the issue persists throughout all gameplay for all the mentioned titles no matter what window type (Exclusive Fullscreen, Borderless Windowed, Windowed).
This isn't a universal issue as it seems to work as intended in CS2, though comes with it's own weird behaviour where my desktop sits at 180Hz after tabbing out of the game.
