Troubleshoot scenes with final gather render slower in Maya 8.0/8.5/2009 than in Maya 7.0

Maya 7.0 scenes that contain final gather may render slower in Maya 8.0/8.5/2009 than it does in Maya 7.0. This is because the new final gather algorithm computes more final gather points for images with a resolution greater than 1000.

Workaround 1: Switch back to the old mental ray 3.4 final gather algorithm using the following command.

setAttr "miDefaultOptions.finalGatherMode" 0

Workaround 2: If you want to continue using the new mental ray 3.5 final gather algorithm, scale the Final Gather Presample Density by a factor of approximately 1000/<image size>. The Final Gather Presample Density can be found in the miDefaultOptions node > Extra Attributes section.
