I looked at the vogons wiki page about cpu-sensitive games. I don't know if that list is outdated or not, but I'm trying to play Scorched Earth and it's running way too fast. There's a setting in the game to alter the speed of only a certain aspect of it (firing delay) but nothing else, and that didn't help my issue. If you're familiar with the game, you press and hold an arrow key to move the tank's firing angle. When I do that, it moves WAY too fast, like lightning warp speed fast. I'm playing this on a 100mhz CPU, so the funny thing is that I played this same game back then on a similar speed CPU and it was nothing like this. Hmm.
