I'm not sure what you mean by Shredder losing on time.

Sound, Announce moves and Comment moves are off. >I bet you don't have a sound card or speaker installed and Shredder is >commenting all of his and Tiger's moves. I do have sound card and speakers installed. This delay happens also when Shredder plays on the portable HP, also with Comment, Announce and Sound off. > This is the only thing I can think of >which can cause the delay. If it's true forget all of your results. The >commenting features "steals" abour 50% cpu time. I see a speed of 110 to 120K NPS in the middle game on the PIII-500, and "computer speed" is 1398. Is this correct? Enrique >Stefan
