FPS Limit for inactive window

[Xizi]

I suggest adding such an option to settings because there are tons of people, including me, who like to keep 3dxchat on while doing some other stuff on PC, be it work/studying/gaming or really whatever else. 

Yes, I know it can be done thorough the Nvidia panel (not so sure about AMD) but it would be easier for users to make it through the game settings and on top of it, Nvidia only letting to make inactive window's fps as low as 20, but maybe its possible to make it even lower though the game's settings to really minimize resources consumption of the game while its inactive.
