PNG or JPEG does'nt matter, I tried both before...
Regarding the gamma value, I do not know, and even do not know how to measure it
; I made no gamma modification on the image (this, I do know how to), built from
scratch : a plain 90% black background (RVB 16M colors) with a rainbow strip
superimposed over a small region.
On the sunny side : POV-Ray 3.7beta23 is 3.71 faster than 3.61c on my
configuration, rendering a moderately complex animation (~6hours (3.7b23) for
1700 images). Thanks to the POV team !
