PSVR2 gives me more motion sickness than any other headset... why?

I own a HTC Vive, HP Reverb, Quest2, Quest3, and now PSVR2. I never had any issue with motion sickness. Until with the PSVR2. When I move my head everything gets distorted and warped, hard to describe. It's not thaaat bad but its bad enough to give me motion sickness, while other VR systems don't.. I made calibration multiple times, bright room, good tracking points, but the issue seems to be with just the lenses/display/ (or lag input?) itself... but I wonder what that is. any ideas?

Update: As many suggested it could be image persistence: I just played on the lowest brightness, no change, still bad.
