Low persistence only gives perfect motion when your eye motion perfectly matches the object motion[0]. For all other motion, low persistence causes false images

Low persistence only gives perfect motion when your eye motion perfectly matches the object motion[0]. For all other motion, low persistence causes false images to be generated on the retina, which can be seen as "phantom array effect"[1].
I think interpolation up to several kilohertz is the best solution, preferable starting from a moderately high frame rate (e.g. 200fps) to minimize the latency penalty and artifacts.

- cubefox 3y agoI think the second effect is quite small compared to the first because CRTs are generally good at the first but don't suffer much from the second, as far as I'm aware.
- mrob 3y agoCRTs suffer strongly from phantom array effect, but individual sensitivity to this effect varies. The people who notice it are the same ones who complain about PWM lighting.
- cubefox 3y agoI think most people don't see this effect on CRTs, so I wouldn't say they (the CRTs) suffer much from it.
