Frame rate suppression
Frame rate suppression is the perceived reduction in speed at which visual information is processed. While under the influence of this effect one may feel as if their vision is lagging and displaying in a manner similar to a buffering video, a stop-motion animation, film strip, a computer monitor, or a strobe light. At higher levels of intensity, it can result in a person's vision temporarily ceasing to move all together as if it has frozen. It is also worth noting that this effect is comparable but not necessarily related to the visual disorder known as motion blindness or akinetopsia.
Frame rate suppression is often accompanied by other coinciding effects such as acuity suppression and double vision. It is most commonly induced under the influence of moderate dosages of dissociative compounds, such as ketamine, MXE, PCP, and DXM.
