Yeah, I am more interested in normal maps, because you can keep your poly count
low and have it compensated for in the map. Where as with a displacement map,
it is more dependent on geometry and poly count.
It seems as though people are using normal maps more so than displacement maps,
especially recently, and with models for games.
I'm trying to figure what will be the best way to go, and it is dependant on
what our engine/milkshape can handle, so I am trying to find a happy medium.

Displacement maps are great for adding fine detail with a normal map, and can
reprisent better detail in some areas that a normal map might not display as
sharply. Combing these two can create some really solid detail that looks
natural without adding as dense geomitry and therefore letting you draw in say
a complex looking architectural design on a side of a wall - bump mapping would
work in part for this, but with the displace map, and normal mapping, you'd get
the feel of the geomitry. Displacement does tend to work better with a bit
higher poly count, but can be a good halfway point to get a little more affect,
and depth.
