It definitely seems something worth trying.

Oh, I had no idea one needs Windows for that. :-/
While games are not really my thing [1], I would image gamers to want 144Hz
monitor with "FreeSync" and configure the game so that he gets somewhere
between e.g. 72-144Hz update frequency with variable Vsync rate.
However, something like that should be done with fullscreen / compositor
bypass.
[1] I'm more into emulators (one of the maintainers for one), those also need
Vsync differing from 60Hz (in my case 50 or 71). Because those frequencies are
fixed during emulator run, changing whole display refresh rate would be one
option there, but "FreeSync" would be nice there too.</pre>
