FBX or Prefabs, Which is best to user for GearVR

Asset & Content Management

when building a scene for the GearVR , is it best to create the in unity Using the FBX Imports, or build prefabs then build the level with the prefabs.

To my understanding Prefabs would help reduce Drawcalls and the CPU load. However FBX build scene seems to load better.

Any info would be appreciated.

If a mesh needs rendered, it does not matter on CPU load nor draw calls, whether the mesh came from a prefab of fbx file.
