I remember someone posting here about a graphic glitch with NFS:V
and the smoke from the tires being green. I have noticed that it is
slightly green tinted on my system. I don't know if this is really a
problem. I noticed on my motorcycle when I broke the rear loose braking
that the smoke off of it was the same color. Grey with a slight green
tint. Maybe it is ZR rated tires that do this.
