Genghis,
Any delay in visual representation of actual (or preceived) motion greater than 100ms will make an aircraft more difficult to control. A (test) pilot will report the delay as degraded aircraft handling properties, but it is actually poor performance of the (simulator) visual system of the PFD generator. The corollary is than a delay of less than 100ms is likely to be acceptable. No reference available I'm afraid, just hard won experience.
