What if you have 8 processors? If you have 8 processors you may start winboard -fcp "wcrafty mt=8 hash=24M hashp=4M cache=2M egtb" What if you have 512 megs of ram? Then you may use larger hash tables which may give you a little more speed. You know that all very well. In any case you don't need a crafty.rc file. You can set the appropriate parameters in the winboard command line or may be the better way in the winboard.ini file. >your crafty can't possibly play any better than with those settings you posted? >What you have done is simply to put some [a tiny fraction of what is available] >of the crafty rc file options on the command line instead of the file.

Vastly? Only if you have a multiprocessor system. Bigger hash tables will not help much in playing fast games. BTW I use a 2 proc system. > >I will admit I was a bit hyperbolic.
