Skyrim: Vulthuryol Battle as a Frost Dragon

Battle with Vulthuryol in Blackreach. For some reason he likes to land early on and stay on the ground. Mod used: Flyable Dragon Races Revamped, http://skyrim.nexusmods.com/mods/17178 I had to turn down the resolution a lot to record smoothly. The recorded video's frame rate is fine, but the flying script slows down when the FPS gets low.
