OLED 240hz lg-27gr95qe-b and G-Sync Brightness Flicker

Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag. List of G-SYNC Monitors.

Your frametime performance in that graph is definitely not consistent enough, and will easily cause visible OLED VRR flicker. You're experiencing some serious sawtoothing; the frametime (bottom row) should be much flatter when the framerate is limited by RTSS or Nvidia MFR.

Do you get less VRR flicker in other games, and if so, what do their frametime graphs look like? Because if you aren't experiencing this in other games on the same system (or less so), it's likely game-specific.
Only some flicker in menus that I have noticed up to this point in other games. Here is Overwatch 2 running at 180 FPS with great frame time and COD at 100 fps and very good times. Any spikes in COD were the start of death cam replays that I was skipping. I am going to chalk this up to Tarkov being Tarkov. But I would love to try and find out what would cause something like this in Tarkov. Especially because it is so consistent and I have seen others mention flicker in Tarkov on this monitor. Maybe I will try to find another Unity built game to test against.

Yup, those are normal.

Definitely Tarkov and/or Unity-specific. There's probably a way to remedy it, but since I don't own it, I can't easily determine whether said remedy can be performed user-side, or must be addressed dev-side.

Again, the Unity engine has been known to have issues with VRR:
