FormulaSim have let me know that they have posted a preview on the beta version of F1RC (of which they have a copy).
From what is said, it appears to be quite good.
You can get to that right here.
Again, Race-Simulator.com have posted some more F1RC screenshots. There is nothing interesting about these as such, most of them are taken when the car is in the pit-lane. See them here.
Remember, feel free to post any comments in our F1RC forums.
