That's good; you get more of a frame budget that way. I saw 90 and even 144 as target frames to avoid VR sickness. It's good to know 72 frames can work too.
Frame rate plays a role - especially when it drops down below targets and stutters, which does happen irl, but designing the experience to avoid motion sickness from the ground up is what makes the difference. Keeping something stable in the view that moves along with head pose like a HUD element while everything else around you is moving makes a huge difference. Seeing the world around you in motion from inside a car with the stable windscreen will be much easier than zooming around through freespace even at 120hz for most people until they get comfortable with the sensory mismatch. I have heard several interesting approaches to acclimatization and can recommend this [1] if you are affected & am told positioning a real fan blowing air on you while in the headset will orient your proprioception in a way that helps.
