I hear it claimed that you're only supposed to enable game mode for competitive multiplayer games -- but I've found that many single player games like Sword Art Online: Fatal Bullet are unplayable without game mode enabled.

It could be my unusual nervous system. I'm really good at rhythm games, often clearing a level on my first try and amazing friends who can beat me at other genres. But when I was playing League of Legends, which isn't very twitchy, it seemed like I would just get hit and there was nothing I could do about it when I played on a "gaming" laptop but found I could succeed at the game when I hooked up an external monitor. I ran a clock and took pictures showing that the external monitor was 30ms faster than the built-in monitor.
