Without VRR should I cap to a frame rate that is divisible from the max frame rate?

Background: My monitor has a local dim option that produces flicker when combined with VRR. So for games where I care about HDR I have been turning off VRR.

My question is, to avoid judder and have evenly paced frames, what is the recommendation?

I have a max refresh of 160 so if I can’t hit that consistently should a cap at something that divides evenly into 160? For instance, 80 or 40. Should I avoid other common frame caps, like 60 or 120?
