The music's fine (MIDI). The graphics, and sound effects, slow down accordingly with caches disabled. However, everything's fine with caches enabled. I'm currently building a twin-BX system. I do have Socket 7 mobos and Cyrix/ AMD/ P1-class CPUs, but I'm cutting down systems to a minimum and optimising parts. So, unless there's a pressing need, I'm not sure if I need a S7 build.
What would be the virtues of a socket 7 build missing from my system? I could test the twin-BXs for anything that's suggested... Right now, I'm looking at a GUS/ YMF724 combo on the slower build: Do S7 mobos have SB-Link ports, for example? The only thing I can think of at the moment for a S7 system is running 'slightly' slower that an underclocked P2@133MHz system...?
Some more tests, same setup:
Mobo: 440BX (with S3 GX2 and sound card only installed)
CPU: Unlocked P2@400MHz
OS: Win98SE
Synth: Roland CM-64
SoftMPU: v1.2; SB220, IRQ5, MPU330

- P2@133MHz, L1/L2 cache enabled:
SoftMPU initialises. Tested on Might and Magic 3, with LAPC-I and SB option.
- P2@133MHz, L1/L2 cache disabled:
SoftMPU initialises. Tested on Might and Magic 3, with LAPC-I and SB option. Intro sound effects and graphics running too slow, however, MIDI sounds fine on CM-64.

These results are the same as the OPTI tested earlier. I'll test the Audiodrive tomorrow... probably the final one, unless there are other requests...?
