New video drivers can have a huge effect on fps. That said, the first thing I would check is to be sure you are using the same video card settings you had when you did your last benchmark, and that you are flying the same aircraft, on the same map. Some of the aircraft in the "Unified Installer" have reworked, higher resolution cockpits that are a bit more fps intensive.

I would also make sure you are not recording video on FRAPS (indicated by fps counter turning red).
