You do not mention Latency (i.e. ping time). For example, Gamers tend to prefer e.g. higher-res mice, because that (supposedly) reduces the time between moving the mouse, and a reaction happening in the game. Presumably now the mouse movement will have to be sent up to the game server, which will then send a response down (many milliseconds, I expect). What was the ping to the Google game server ? Did that make the game feel "laggy" ?
