With growth in interactive network games comes increased importance in a better understanding of the effects of latency on game performance. While previous work has measured the effects of latency on first-person shooters and real-time strategy games, there has been no systematic investigation of the effects of latency on sports games. In this work, we study the effects of latency on online Madden NFL football, one of the most popular online sports games, through a series of carefully designed experiments in which we systematically control latency between players. Our experiments illustrate the mechanisms Madden NFL uses to compensate for latency. Our user studies show there is little impact from latency on user performance in Madden NFL over typical low Internet latencies. However, for latencies higher than 500 ms, there is a significant impact on user performance, degrading performance by almost 30%. Our network measurements show periodic data rates during game-play with significant command aggregation at higher latencies.
