I'm running out of ideas too. I played aroud with your settings here and
my very simple test scene but found no solution for the riddle.
Meanwhile I think that there must be an other problem and the water
material is the wrong track. But I have no idea what it could be. I
first exchanged my water material by yours given here. The computing
time decreased (!) to 6m 41s. Then I added your fade_distance and
fade_power to my dimmed light_sources: 6m 41s. But you may have another
scaling (for me 1 unit=1 meter). Then I worked through your command line
options. Your higher anti alias settings yielded 8m 21s. Adding +bm2:
9m 58s. -rvp saved 32s. +p should not have any effect on the computation
time but indicates that you are not running the Windoze version like me.
All computations mentioned above done with this insane IndoorHQ settings.
