Totally wrong newsgroup; setting followup to povray.general.

You could either keep it in separate files, or use #if statements.

On main scene:
#declare UseHighQualityModels=no;
#declare UseHighQualityTextures=no;

On an included file:
#if(UseHighQualityModels)
  #declare Model = union {
   ...something BIG
  }
#else
  #declare Model = union {
   ...simplified model...
  }
#end

object {
  Model
  #if(UseHighQualityTextures)
   texture {
    ...something BIG
   }
  #else
  pigment {
   color Yellow
  }
  #end
}
