This is especially true for 120Hz FreeSync.
Larger VRR ranges (e.g. 48-240Hz) will have fewer LFC stutters than smaller VRR ranges.
For divergence between gametime:photontime -- the stutter penalty is 1/120sec for LFC on a 120Hz VRR display, and the LFC stutter penalty is as little as 1/240sec on a 240Hz VRR display. So wider VRR ranges really help.
