When you use faster hardware (or longer time controls, that's the same), Genius
is even less competitive.
My own experience.
Chess Genius has a kind of "explosive" power. It will find some combinations in
0.01s when other programs need 0.5s on modern hardware. But from then it gets
worse. In general if you expect a modern program to need one minute to find a
combination, expect Genius to need 2 or more.
I have an idea about the origin of this problem, but I'm not certain.
Anyway you can get a clear picture of this by doing the experiment and compare
solution times with other chess programs. "Easy" combinations: Genius does
better than other programs (but it's extremely hard to measure on modern
hardware because we are talking of hundreds of seconds). "Hard" (deep)
combinations: Genius is generally behind.
Again: I would have been very proud if I had been able to write a program like
Chess Genius. The achievements of Richard Lang, still today, amaze me.
