I won't argue the point if you feel this within your threshold of pain, but I urge other readers to not go in this direction.

Pixel response and input lag are worse or better at a refresh rate depending on monitor, some are worse, some are better. LFC engage/disengage/flicker is far worse of a problem on this monitor.

Other monitors have different characteristics.

There is nothing worse about this monitor below 80Hz. Flickering also does not begin until about 35Hz, which would require setting a limit of 25Hz~, as LFC kicks in roughly 10Hz/fps above. Nobody plays or wants to play games at this low framerate anyway.

Yes, I forgot to mention this, but only because in this scenario it's even easier and much wiser to simply frame limit around the LFC on/off threshold. With the monitor in stock configuration, if you can't keep a game over 80fps consistently then limit it to 75fps and you've solved the problem.

Changing the variable refresh range lets you play with where you'd need to set your frame limit; if you've got a decently beefy PC it might be desirable to have the range around 105Hz-240Hz for example, such that you can target 120fps (or higher) in lighter games, and frame limit heavier games at 100fps.

I have a 3080 and 5800x, a game like Cyberpunk 2077 maxed out can drop into the 50's, 1440p. I could set the limit to 120-240Hz but I don't think that would even always keep me in LFC mode as I'm sure it goes above 120fps sometimes, I'd have to cap framerate... and then I have to go into CRU to change limit when I want to play another game that isn't always above or below 120fps...
You want to always have LFC engaged, or always have it disengaged.
Not engaging and disengaging while you're playing a game, at least on this monitor.

Avoid instantaneous doubling and halving of Hz.
I guess other people can adjust their framerate caps and lower/raise their VRR/LFC floor on a game by game basis if that's not beyond inconvenient to them...
