Adjusting the refresh rate to the performance of the desktop is one.

That's the definition, isn't it? Why is this better than a fixed refresh rate? Can the monitor scale the rate down to consume less power or something?

I also heard it would make it easier to manage multiple monitors sporting different refresh rates, although I haven't had issues with that personally.

I heard that too and got similarly confused. I work with two monitors with different refresh rates (75 and 60) on Mint and it seems fine. Is X downgrading my 75 Hz monitor to 60 silently? I don't know how to check that.

    1. To avoid having to skip frames to make the desktop look more fluid, thus matching the refresh rate of the monitor.

    2. I think the whole desktop runs at the higher refresh rate when you have mismatched monitors? Not sure. Wayland and X11 might differ as well on how they handle this.

    Can the monitor scale the rate down to consume less power or something?

    In theory, yes. However, I have never seen it used that way. The only widely used applications for VRR are games and video playback.

    Would be interesting to do some power measurements though.

    Is X downgrading my 75 Hz monitor to 60 silently?

    Yes, X does not support different refresh rates. Wayland does.
