Sure it does - gravitational lensing, etc.

I guess more precisely, GR can't predict the interactions between particles, only the interaction of particles with gravitational fields. But GR can't predict the behavior of two colliding electrons - it will make similar predictions to classical physics, not the Schroedinger equation.
