Does SM 3.0 Far Cry use true displacement mapping?

I think Tony Tamasi said it uses virtual displacement mapping in a TR interview but even if it uses virtual DM it can still use true DM on other parts.

Its parralex mapping I believe which isn't true Displacement mapping. True displacement mapping generally means all the surfaces are tesslated to sub pixel triangles which you ain't gonna see for a while.

FC doesn't use any kind of displacement mapping even with shaders 3.0.

what do we call moving vertices according to a height/displacement map?

Heightmap its sub-pixel so its not true displacement map.

No current consumer graphics chip is capable of doing displacement mapping in hardware.

... Parhelia? *sniff*

Maybe he means with any worthwhile speed in real world apps?

Who says it did it in hardware?

Matrox, who else?

So you used "current" to exclude NV40, did you?

no current hardware can do true displacement mapping with enough speed to be useful in a real game
