I know. What I wanted to see was if "old" programs which are not tested on
actual hardware by SSDF is still able to compete with actual programs.

Personally I say YES after this small match.

And another point is that Genius3 does NOT seem to be weaker than Genius5.
So all guys searching a cheap but strong program look for Genius3 e.g. and let
it run on your fast PC. :-)
