OK.

Nobody answered, so i've tested it out by myself.

The answere: a clipfactor of 999'999 is the maximum.

I've tried to use a higher value, but if i use for instanve 999'999'999
every object clips away from the beginning.


SO this is my question now:
Is there any way to use a higher value for the view-frustum?
