In Chess Tiger's case I have matched it against itself using two different sets of hardware to see how well it scaled. I used a PIII 900 vs a PIV 2.6 Ghz. The match of 200 blitz games ended in a dead draw. The reason I did the test was that I have used Tiger since version 11.9, and my hardware gets upgraded atleast once a year. I have noticed no rating difference while playing online when using different hardware. Other programs like Crafty, Ruffian, Gandalf do indeed profit more from better hardware. I just don't think that Tiger is one of them. This could possibly be the reason for Christophe's thoughts on the time control difference. Peter.
