Looks like a pedestrian (walking person) is the source of glitch and could be corrupt game installer, get another copy of this game again?

Cheers,

issue maybe is that the game require a very old driver like Detonator 6.xx or 7.xx and your cards are too new to run those drivers. Yo maybe able to mod 7.76 cdrivers to work the the geforce 3

Open the file "NVAGP.INF"

Look for [Mfg] and add this

[Mfg]
%NVIDIA&DEV_0200.DeviceDesc% = NV20,, PCI\VEN_10DE&DEV_0200
%NVIDIA&DEV_0201.DeviceDesc% = NV20,, PCI\VEN_10DE&DEV_0201
%NVIDIA&DEV_0202.DeviceDesc% = NV20,, PCI\VEN_10DE&DEV_0202

Look for [Strings] and add this

[Strings]
NVIDIA&DEV_0200.DeviceDesc="NVIDIA GeForce3"
NVIDIA&DEV_0201.DeviceDesc="NVIDIA GeForce3 Ti 200"
NVIDIA&DEV_0202.DeviceDesc="NVIDIA GeForce3 Ti 500"

The plain GeForce3 should be in there already.

Try that very old driver and see if it work with the game on that card. Its the only card you have that can run it. Also try just running DX 7. not 8.

Report back here with your findings.

The glitches exists with all Geforce cards, even with the oldest drivers I can find. Those distorted polygons come from pedestrians. If you disable pedestrians, the glitches go away, but then you're not playing it "the way it's meant to be played."

The alternative is to use a non-Geforce card. Like an AMD/Ati, 3dfx, Matrox, or a TNT Nvidia.

Can't you switch them off in Modtown Madness?
IIRC, you can switch off almost everything and have to town all to yourself.
I can't remember that well, because it's been over a decade since I last played the game.
