I would probably try the oldest drivers with support for that card, maybe slightly newer, but not as new as 81.98 which is probably the latest nVidia driver for ME and supports cards as new as GF 6xxx.
Looking at http://www.vogonsdrivers.com/index.php?catid=24, drivers from 08.05 on support GF2 MX 100.
Newer drivers might enhance compatibility for newer games,
Any reason you are using an MX 100 and not at least a full MX (MX 400)? The MX 100 has less memory bandwidth than all previous nVidia cards, including Vanta LT. I suppose a balanced card would be a full GF2.

No real reason other than cost, up until now -- I've decided to give the machine a bit of an overhaul and use it to replace my main retrobox. Purchased a slotket, found an old Celeron 1000 I had been holding onto, and found a cheap Radeon 8500 (would have likely gone with a GF3Ti or 4Ti4200, but those are apparently astronomically priced in my neck of the woods). Slotted a SB16 (CT2940, sadly it does have the hanging notes bug) into the ISA slot for DOS mode, cleared two PCI slots for eventual V2SLI goodness, and cleaned up a S370 cooler and gave it all a test fit on a junk board, and as we speak I sit waiting for the parts I ordered to come in the door.

That said, I found 45.23 to be a good in-between point, as 81.98 was apparently CPU-intensive enough to make Unreal Engine 1 games run very poorly, but I don't want to run into any pitfalls by using such outdated drivers as the very first ones to support the card.

Good choice. The 8500 with Cat. 6.12 can be a bit faster then the GF3Ti. Re: 99-03 video card performance scaling (Q3, Unreal, DK2, 3DM2k, 3DM2001)
