Reder takes 80% for the last line

I have a weird problem. For a frame that is rendered in 1sec it freezes for another 5 sec before the render is finished.

I think I turned everything off, but maybe I’ve missed something.

If anybody can help I would appreciate very much.

Are you rendering a single frame or an animation?

If your rendering using the Anim button, the extra time could be the time it takes to save the image to your harddrive.

Maybe it’s just taking long to render raytracing, etc.

I found the cause. I had some lights dupliverted for volumetric light and didn’t switch on “layer” so they where calculated though they where on a hidden layer.

Weird thing is, that they slowed down the calculation only in the very very end, when the render of the picture was 99% finished…
