Frame rendering getting higher and higher

[seb6996]

Hi,

I really don't understand why rendering these frames is getting higher and higher time ! See the capture.
This is only a camera movement, some floatings in the air and a light with various power. Maybe the problem is some where else.. But where ?
Any reasons to explain that ?

Thanks

Heat. Render first frame 10 time and compare times.
