How much delay is there really in current games?

Abstract

All computer games present some delay between human input and results being displayed on the screen, even when no networking is involved. A well-balanced discussion of delay-tolerance levels in computer games requires an understanding of how much delay is added locally, as well as in the network. This demonstration uses a typical gaming setup wired to an oscilloscope to show how long the total, local delay is. Participants may also bring their own computers and games so they can measure delays in the games or other software.
