Depends on the hardware, I think. A pimped out PC could probably manage. Though I also think I recall some spokesman (maybe Howard himself?) stated before Skyrim was released that there would be no dragon mounts, because they felt that trivialized the dragons.

A community-made Dragon Mount mod is probably more likely.
