There does not appear to be such a setting, and the closest earlier topic I could find on this subject is:

ps. Sometimes, chrome's internal flash will conflict with adobe flash making moves very laggy (disabling chrome's internal flash might overcome this).
Is there a way to change the speed at which the moves are animated while playing? When I play in Internet Explorer 10, the moves seem to happen instantaneously, but when I use Chrome they take a good quarter of a second to move across the screen, which is extremely annoying. Is there a setting somewhere in Chrome or on chess.com that can fix this?
