I do know that these problems can exist in old games, but I doubt Freelancer is old enough to have problems with any high-end video card on the market. There might be some problems with drivers or other hardware/software, and if there's going to be a problem, that's probably where you'll get it.
I do remember trying to play Sim Copter with my Nvidia 7600 and it ran fine, but my processor was too fast so it jumped around and lagged a lot (kind of ironic, methinks).
