It was certainly good enough for millions of other people. What makes your eyes super sensitive to fps?
Maybe something's wrong with my mind? But 24/25Hz, even with the correct shutter speed, is noticeably causing strain to process, while e.g. old school TV productions at 50Hz don't have that issue.
And stereoscopic 24fps look twice as bad.
I think you can notice high frame rates. Difference between 60 and 120 fps is striking. Even between 90 and 120. And everyone I was showing my phone that does 60, 90 or 120Hz could see it.
Conversely I don't see much difference between 120 and 240 fps.
