I've finally found out why my framerate takes a nosedive when capturing minecraft and some other games. Exiting Raptr I don't see any problems with game capture. I've tried going through the settings but as of yet have no found any options to turn off whatever may be hooking into my games and causing problems.
I'm not using GeForce Experience or the new Steam capture beta either.
I have the same issue. Is there any solution?
I stopped using raptr ages ago, I dunno if it's been fixed, the lack of replies on this matter leads me to think not.
