It took between 10 and 15 mins. to get to this depth. I wasn't watching closely but it was about 2-3 times what it took crafty to get there. Apparently the elapsed time is off. BTW, I'm running on a Gateway notebook, 700MHz, 256M memory. Oracle is running in the background but isn't doing anything. > >The B.46 CB natives reaches depth 11 in a few minutes on Athlon/700. >The evaluation looks quite different too. > >I guess that there is something wrong with the comet-xb. > >Sorry, it seems i was too optimistic to try this release without testing. Actually, this is the first alternate engine (other than crafty, I haven't tried any others though either) that I have running under SCID so it's a success from my standpoint, the engine needs to be tweaked though.
