This can generate a _lot_ of screen I/O and scrolling can be inefficient. It might be that the AMD is getting killed here. I know of no reason why the AMD would be slower executing crafty, based on results I have seen from others that use these processors... maybe an even better test would be to reboot windows in dos-mode so there is no windows stuff going on at all.. >hash table memory = 48M bytes. >pawn hash table memory = 10M bytes. > game/30 minutes primary time control > > >Crafty v15.20 > >White(1): edit > > +---+---+---+---+---+---+---+---+ > 8 | | | | | | *K| | | > +---+---+---+---+---+---+---+---+ > 7 | | | | | | | | | > +---+---+---+---+---+---+---+---+ > 6 | | | | | | | | | > +---+---+---+---+---+---+---+---+ > 5 | | | | | | | | | > +---+---+---+---+---+---+---+---+ > 4 | | P | | | | | | | > +---+---+---+---+---+---+---+---+ > 3 | | | | | | | | | > +---+---+---+---+---+---+---+---+ > 2 | | | | | | | | | > +---+---+---+---+---+---+---+---+ > 1 | | | | K | | | | | > +---+---+---+---+---+---+---+---+ > a b c d e f g h > >White(1): display >White(1): go >end-game phase > clearing hash tables > time limit 51.42 (5:08) > depth time score variation (1) > 9 0.07 2.21 1.
