Hi Jan,

I added that line to my photon global statement, and so far, I recognize 
that POV-Ray behaves very different to how it was doing the map before.

Yes, there is a clear speed bonus, I recognized that when setting POV to a 
resolution of 160x120. Now I have started at 3200x2400, and wait until some 
result or crash comes. The blocks of photos are now much smaller (before: 
ca. 40,000 before each break, now only 320). I will keep you up to date.

Sven
