Retina refresh rate is extremely high! 5-digit Hz. Kudos to techless for fantastic video (39,620 Hz, though estimated ~20,000 Hz a few years ago). There are 4 main visibility thresholds. Expand this post to dive into rabbit hole for a moment 🕳️🐇ִֶָ

Instructions for Mac users of TestUFO with stutters. There's a new "High Power + High Precision" mode for MacBooks, via gear icon. Many TestUFO animations run as little as 0.1ms-0.2ms but stutters at 120fps 120Hz due to Mac power management. This very XCKD setting (#1172) fixes TestUFO stutters.

60fps vs 120fps = 2x motion blur difference at GtG=0.00ms. Non-zero GtG pixel response adds blur, even if less than refreshtime. 1. 60fps vs 120fps weak on overdriveless mobile LCDs (~1.2x) 2. 60fps vs 120fps more visible on gaming LCDs (~1.5x) 3. 60fps vs 120fps very visible on OLEDs (~2.0x)
