Help me appreciate MFG

Recently upgraded to a 5000 series. I had heard some good praise for MFG from those who had this series, but in the few implementations I tried, it was very noticeable that it was generated frames.

Running around, I could see things like my static compass and health/stamina bars look like they're pieces of cloth being blown around by violent wind.

In another game, shadows and other colors at my feet looked like rushing water moving along with me, massively pixelated.

Is this perhaps more of an issue if I'm pushing MFG too hard? ie - if I were to be getting something like 40fps and I'm using MFG to get to 120, is it too many generated frames to look good? And thus adjusting my quality slightly will help?

Or, is this just a bad implementation for the particular title I'm playing? Is this actually even a title by title implementation, or is the global rendering pipeline the same?

Just looking to appreciate it as that was originally what seemed like a big draw for the 5000 series cards.

Thanks!
