I try to render one flyby camera animation that basicly consist in one camera with one helix path flying arroun one object, every completed spin the camera moves up and so on.

each turn has 130 frames, and the total frames sum 1430 or 11 turns.

The configuration for AA and indirect illumination was llitle tweaked over the default settings.

I use the multi frame/camera fly option saving the prepass, the first frames time to complete the prepass was arround 90 seconds but now checking the progress arround frame 400 the time reduce drasticly less than 20 sconds! why in Finalrender aQMC engine the amount of time of that prepass was sustancialy reduced? I forget to check uncheck something?

the prepass in final render is additive, it builts on the previous light data, and then adds on to it when it finishes the next frame. The more data you collect from the scene, the less time it would need to calculate from the a slightly different angle from the same scene. Thus the time in the subsequent frames are reduced.
