>I would feel woozy and that's when the framerate dropped below 75-80hz. The 144hz option is the greatest thing, I almost got a Rift S but saw the 80Hz and fucking noped out of that shit

You're confusing framedrops with consistent FPS. In the first place, the Lenovo headset and most displays can't dynamically switch to different refresh rates. It's locked to 90. So you get issues similar to slow panning scenes in movies (23 fps) that stutter horribly on your monitor if you're not hitting the full framerate. When the system can't generate the full native framerate, it has to take old frames and that results in stutters. Your eyes and brain are following the scene smoothly and suddenly it moves in a way your brain doesn't expect (the stutter). That's what caused motion sickness. There is little scientific evidence that suggests a consistent 80 FPS on an 80 Hz headset causes appreciably more motion sickness than a consistent 90 FPS on a 90 Hz headset.
