Dual monitor (FPS issue)

[Loxa]

Hey, I have a BenQ XL2411T & LG Flatron E2351. When for example i am playing League of Legends on the BenQ monitor and have a webpage open on the LG screen it will affect my FPS slighty until i tab the webpage down on the LG screen ( 77fps while page open 144fps when page tabbed down ).

I'm just curious if there is some kind of overlapping going on?

I don't play LoL but on a lot of games there is a setting for max background fps, perhaps it's that?

I'll have a look into that, cheers.
