Because you're causing a massive number of collisions by running the card

If you also have the card set to full-duplex under NT, then either the
NT driver is refusing to do it when you tell it to, or because of some
oddity of its transmit path logic you're just not losing as badly as you
deserve to.

As an art school alumnus, let me inform you that Ethernet hubs *are*
half-duplex, whether you're an electrical engineer or not.
