Did that just now and the issue is "gone", as long as you're above 50Hz. I think the monitors VRR was from 48-240Hz, so if you get to close to the lowest range, it also flickers. If you get out of the range (below 50Hz), the refresh rate goes crazy again, obviously.
Conclusion to me: LG could fix this by "optimizing" the gamma curves for each refresh rate in the whole VRR range. That way the darker colors wouldn't be washed out as well, if it's at the lower spectrum darker areas are quite bright with 55Hz, compared to 240Hz.
It may not be gone completely, due to variances in models, but it would be way better than it is now, where 55Hz looks like a TN-panel in dark levels.
I wonder if ASUS did it different with their OLED model, since it has the same panel..
Did that, exactly as you described, since this offers the lowest latency and best compatibility with games, iirc.jorimt wrote: ↑31 Mar 2023, 11:30That said, to rule out any G-SYNC configuration issues, ensure you're using G-SYNC "Enable for full screen mode" + NVCP Vertical sync "On" + a framerate limit at least 3 frames below the current physical refresh rate (I assume you're using a 50 FPS RTSS limit in the videos).
Windows 10, but a modified one (Ghost), though I never had G-Sync issues on it.
I didn't do any messing with fullscren optimizations, since all my testings with with it gave me less fps in games and more stutters, so I left it at that. Though that's probably due to my CPU (TR2920X), since results on my old i5 3570k@5GHz were different.
One last question. RTSS vs NVCP frame limiter, how do they compare?jorimt wrote: ↑31 Mar 2023, 11:30Long story short, the worse or more sporadic the frametime performance is in a game, the worse the near-black OLED VRR flicker will be.
The only way to avoid this on current-gen LG OLED panels during VRR operation is to use an external limiter like RTSS to set an FPS limit that can be sustained 99% of the time in the given game.
I.E. you want the RTSS limit to be the framerate's limiting factor the majority of the time. As long as it is, RTSS will stabilize frametime performance, which should reduce the near-black flicker to a minimum.
If I recall correctly RTSS has a 1-frame-latency and nvidia inspector had 2-frames-latency (very old information, might be different now). So I'm kind of curious if the result with NVCP and RTSS would be the same in the end, or if one has the upper hand.
