A very interesting analysis for geeks. It links to many articles (including by Valve Software) and scientific papers, as well as touches upon why ultrahigh frame rates (e.g. 1000fps at 1000Hz) is the only way to achieve flicker-free low persistence without strobing, phosphor, black frames or similar light modulation.
