Thank you so much. I come to know some of the "flicker" may not due to the DELAY. Sometime, the sprite moves in a high speed so that the moving is not continuous in the nearby frame and looks like ficker. > > Most lcd panels seem to be 60Hz or similar.=20 > So 0.01 (100Hz) is probably still wasteful, as you might render 100 > frames of which only 60 will ever be displayed, 40 may be lost entirely > - that's pretty wasteful... > > In which case, 0.017 might be worth a shot? > Though, that's about 59Hz, so depending on how your graphics card > handles things, that might actually beat really horribly with the 60Hz > monitor refresh, so... > > And note that 0.02 is not 1/25 (or 25Hz), it's 50Hz - twice as fast. > > To be honest, I'd be surprised if most people noticed the flicker at > 0.04 (which is 25Hz) in practice on a typical monitor, especially the > current crop of lcd monitors... > > > > SELEX Galileo Ltd > Registered Office: Sigma House, Christopher Martin Road, Basildon, Essex SS= > 14 3EL > A company registered in England & Wales.
