Abstract

This paper describes the effect of latency on the performance in League of Legends. We ran some pilot tests to determine that the best metric for a player's performance in League of Legends is ability hit chance. We then created a calculation method for the deadline and precision of an ability of a champion in League of Legends. Deadline is calculated as the time it takes to finish an ability; precision is calculated using the area of effect of an ability over the screen size. We ran a user study for a few chosen abilities to measure the performance of a player at different levels of latencies. We then analysed the performance data collected from the user study to find out a correlation between an ability precision and deadline characteristics and the effect from latency to the ability hit chance. Our results suggest that deadline has more impacts on performance than precision. From the results, we also formulated a function of decision and deadline which has an exponential decay relationship with the effect on the ability to hit from latency.
