On the top right of the start screen of the 'Geforce Experience" is the shadowplay tab. Is this grayed out? If so, which card are you using, must be before the 650. If that's true, then what "new" card did you get. If it's false, then click the shadowplay tab and flip the switch in the little window that pops up. Shadowplay will NOT hurt your fps, no matter the game, but it's always a good idea to write to a different disk than you read from. Most pros use a scratch disk with a fast write speed and decent capacity, at least a 7200rpm 500Gb drive. Those cost about $40. If you can't use shadowplay, because you bought a AMD card, then I'd get a different HDD and tell fraps to record to it. That should solve all problems.
