A game won't jump between 60 and 120. It's gonna be more like running at 70-90fps and maybe sometimes dips below 60fps. But that's fine because that's what variable refresh rate is for. Or what you probably want to hear; a game jumping between 60 and 120 is not gonna be worse than a game running at 60.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
