Camera.Renderer: file read causes a huge performance drop

I don't know why the Camera Renderer has to open and read a file in the middle of the game play. I don't know the internals of the engine but I understand there should be a good reason the read some data from a file during the camera rendering process, however I don't see why the file has to be open in the middle of the game play instead of at the game's start up, where's the player won't notice a few extra milliseconds.



As you see opening and reading the file in the middle of the game play causes a 141ms spike, and 109 of them are taken the the File.Open operation alone. The read operation takes 31ms, so if the file was opened at game start I would be seeing a 31ms spike instead of a 141ms.

 

I working on that, but since it doesn't occur all the times is kind of hard to figure out a reproduction case... however be sure I'll file a bug reporte as soon I have a reproduction case identified.
