When Nvidia replaced the longstanding GeForce Experience App with a new, unified Nvidia App last month, most GPU owners probably noted the refresh and rebranding with nothing more than bemusement (though the new lack of an account login requirement was a nice improvement). Now, testing shows that running the new app with default settings can lead to some significant frame rate dips on many high-end games, even when the app's advanced AI features aren't being actively used. Tom's Hardware noted the performance dip after reading reports of related problems around the web.
