If you are using a static scene, radiosity artifacts should be
comparatively easy to get "static" by saving radiosity data and re-using
it from frame to frame. Beneficial side effect is a good deal of speedup
for the rendering, as radiosity has to be sampled only for areas that
hadn't been visible to the camera in previous frames.
You might also want to do a first low-fps low-resolution pass to gather
radiosity data, and then use that in the high-resolution render proper.
