A recent study concluded that 120fps is the "important threshold" to avoid VR sickness for most people. The paper comes from Xi'an Jiaotong–Liverpool University in China, where the authors have been studying the effects of VR refresh rates, resolution, haptics, stereoscopy, and more for years, including how these elements all relate to simulator sickness. A Pimax 5K Super was used for the study because it supports up to 180Hz refresh rate, the highest of any headset on the market. The study tested 60fps, 90fps, 120fps, and 180fps to compare the effect on sickness for the 32 participants, 16 male and 16 female, aged between 18 and 51. It found that 120fps is an "important threshold" after which the participants reported significantly reduced nausea compared to 60fps and 90fps. At 180fps the reduction in nausea was minimal, suggesting 120fps is the threshold.
