[citation][nom]WarDaft[/nom]How can people say FPS is unimportant for SC2 because it's an RTS?Responsiveness is probably more important in SC2 than in any other game on the market.[/citation]
You misunderstand. Responsiveness is not the same as FPS.
In an RTS, your success doesn't depend on targeting someone's head with a mouse. Lower FPS can really mess with precision, lightning quick targeting.
RTSs tend to be more about quick management of units, not precision targeting. FPS is not as important in an RTS, certainly it should be smooth enough to play well, but it doesn't have to be lightning quick to prevent a disadvantage.
