It is very hard for others to answer your questions. You should be the right man to find the reasons and report them :) Here are only my guesses: - Your program may be worser than your rivals in longer time control. By using faster computer and using the same time control, it turns out that you play a longer time control games in your old computer. - (more technique) Your search is little worser than the rivals, making some gaps of search depths. In the old computer the difference may be very little, say 0.5-1 ply. In the new computer when your program can search deeper, say 1 ply, but your rivals could search more 2 plies. Thus the gaps between yours and the rivals are expanded to 1 ply, or around 50-70 ELO.
