I cut the calulation time for the shadow-map to about 3 seconds.
(depends of course also on the PC, but the calculation should be done under 7 secs on older
computers)
Still having quite smooth shadows.

The level is fully made in the editor, wich took me about 1 minute...
(its still missing ambient objects, like trees)
