Question Capping the framerate causes VRR flicker ?

I have a really odd problem. Whenever I activate any form of framerate cap, either manually through Nvidia control or RTSS or automatically when a game uses Nvidia Reflex, my refresh rate of the TV starts to fluctuate wildly (seee videos below). This in turn causes severe VRR flicker as naturally the reefresh rate is all over the place even though FPS and frametime are stable.

I am really out of ideas what could cause this. I have reinstalled my drivers multiple times and even did a fresh windows install but nothing makes a difference.

Of course, disabling V-Sync or G-Sync gets rid of the flicker but that is not really a solution.

The odd thing is that everything was still working early this year, but somehow even rolling back drivers did not fix the issue. I am suspecting an update of my LG G2 TV's firmware [bad language removed] messed everything up, in which case I am kinda stuck waiting for them to fix it (if they eveer do).

Any advice would be much appreciated.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Did you reinstall the OS in offline mode so the OS doesn't download and install drivers it thinks is right for your platform?

but somehow even rolling back drivers did not fix the issue
What driver version are you on at this moment of time? Did you use DDU to remove all GPU drivers prior to rolling back your drivers?

Hi sorry for not including it in the OP.

CPU: AMR R7 9800X3D
CPU cooler: Arcit Freezer II 360 AIO
Motherboard: msi mpg x870e carbon wifi (BIOS v. 1.A30)
Ram: G.Skill 2x 32GB DDR5 @ 3200MHz
SSD/HDD: 2x Samsung 990 pro (2TB) + 1x Samsung 870 Evo (2TB)
GPU: MSI RTX5090 Suprim X (Driveer 577.88)
PSU: Seasonic Prime TX1300 ATX3.1 (2025)
OS: Windows 11 Version 10.0.26100 Build 26100
Monitor: LG G2 77"


I used DDU each time I reinstalled drivers or rolled them back. I am also currently on a completely fresh Windows install but I did not install it offline. But wouldn't DDU take care of any wrong drivers?
