Not sure if this helps, but...
From the docs:
"The usage for this pre-render setup is straight-forward. A new and optimized scene file is generated and is ready for the renderer. See the following maya -optimizeRender -help message:
Usage: maya -optimizeRender [options] mayaFile optimizedMayaFile
-botRes 'int'
Minimum file texture resolution that will cause BOT files to be produced. For example, specifying "-botRes 256" means that all file textures bigger than 256x256 will be converted to BOT format. The default value is 0, meaning all file textures will be converted.
-botLoca 'name'
Directory in which BOT files reside (default is in the same directory as the original file).
-help
Prints this message.
-noBOT
Avoid BOT creations.
-noCleanup
Avoid cleaning up useless data.
-tessFreeze 'start frame' 'end frame' 'by frame'
Calculate NURBS tessellation that gives the best image quality based on the camera projection."
