they're both 30 fps, dude, but underworld doesn't tear like a mofo. underworld has nice, gradiated shader-produced character and detail shadows instead of nasty stencil shit. the animation, modeling and special effects are leagues above uncharted's ghoulish hyperencephalic look, hideous special effects, and horrible cariacatured hand animation. textures look roughly equal, although uncharted abused normal mapping in a sort of icky dx8-esque over-the-top way.
