This game is speed sensitive. You can try shutting down the cashe with setmul or using throttle to slow down.

I suspected that as well. On my PIII-800, the SetMul does not seem to do anything. What are my other options for slowing down this system?

Well the INTEL chipset, although very stable and compatible, does not work well with either setmul or throttle. I tried, a long time before, using a via chipset slot one motherboard and, while the slow down utilities worked, the system became VERY slow. The same applies to socket 370. The best thing i did is that i found a VIA MVP3 chipset motherboard with agp (a bit buggy but works nice with voodoo 3 agp and geforce2 cards) and stuck an AMD K6-300 in. Throttle works wonders and setmul is doing a good job, while still on par with Pentium 2.

UPDATE:
I was able to run the system perfectly with using SetMUL L1D command, instead of using Phil's (Phil's Computer LAB) per-configured batch files (i.e. Slow, Slowest, etc.), and now the game works!

Nice! The same applies to day of the tentacle and indy 4.
