As presented in this paper, the segment tracing algorithm produces significant performance gains over regular sphere tracing by adapting step size to SDF geometry.
This requires the ability to calculate extra data about a given SDF, namely its falloff function, and consequently its lipschitz bound with respect to a ray or segment - this should be feasible to encode as a custom attribute.
