Have you enabled them in the video settings menu? If you did and they don't appear - it's sort of a general fact that nVidia cards and certain Forceware driver versions don't perform well on Halo. Many do not draw invisible players correctly, and some don't draw particles or lighting and shadows very well.
I think that maybe trying an earlier driver version may help. You can always go to the NGO website, see if they have forums, and pose the question there. They'd probably know.
