Our own experiences with the thing felt a bit more laggy, and now Eurogamer is echoing those impressions and putting a bit of science behind them courtesy of a 60fps Kodak Zi6 (http://www.engadget.com/tag/kodak,zi6) camcorder. By filming the controllers and their on-screen representation, the site's tireless statisticians calculated an actual lag (including that of the display) of 113ms -- closer to 10 frames if a game is running at 60fps. Naturally much of this is thanks to the rendering of the result and not just the Move, but according to a 2008 GamaSutra test we found (linked as "More Coverage" below), the controller lag from the standard PS3 controller varies widely from game to game, with GTA IV measured at 166ms -- almost 50 percent higher than seen by the Move. So, while we can't draw too many conclusions about this single-game test from GDC, we can give a little advice: get back to beating up some underworldian goons as Kratos and don't worry about it.PlayStation Move controller lag detected, analyzed (http://www.engadget.com/2010/03/18/playstation-move-controller-lag-detected-analyzed/) originally appeared on Engadget (http://www.engadget.com) on Thu, 18 Mar 2010 10:28:00 EST.
