Max background FPS setting

[ricoexo]

Is there a way to increase my max_background fps? i stream on twitch and when i start doing things on my 2nd monitor my game drops to about 10-15fps.Its not because my PC cant handle doing what i do,because my PC temps actually go lower while the FPS drop happens and i use 2nd monitor.I know games like World of Warcraft have options to set ur max foreground and background fps and i believe this is what my issue is.I know the ingame options do not have the ability to change the setting but is there a file/folder in my directory i can fix it in?
