Long time ago, but I now was was back in the topic. What I have found out that it has actually nothing to do with the FSB..at least i think so. I have bought a celeron 400 to try out. and the result is the same.

what interests me, the game with i was fiddeling was Grand Prix 2. on my 667mhz the game run perfect. clocking down to 333 via FSB had some struggles especially in Monaco. The same results with the Celeron. Is it possible that 300-400 mhz is just too slow? i mean this game was made for P1 CPUs and should run on those "higher" CPUs smooth?

People's idea of "smooth" was very different back then. Not familiar with this particular game, but... I would say 2-3X the MHz of the 'recommended' configuration on the box is probably a reasonable rule of thumb for good performance for late 1990s games?

Keep in mind that we're talking about an era where CPUs went from 233MHz to 450MHz in less than 18 months and 450MHz to 1GHz in... less than two years. It's only about three years from 233MHz Pentium MMX to 1GHz PIII.
