And with VRR in general it matters a lot less if you have a steady framerate. Pretty much my only complaint with the steam deck hardware is that it is not a VRR display. Much like with dlss/fsr, freesync/gsync is perfect for when you are running an emulator with wild performance swings or at the limits of your hardware.
And, back in the day, you could do weird stuff with telling windows that your monitor had a different refresh rate to do this but it was far from pretty and prone to strange behavior.
The AMD driver can cap your game framerate globally, 90Hz instead of 144Hz saves a lot of power but is still much smoother than 60Hz
