Will come the feature of Subdivision Displacement in future ?

hi, this is very difficult to implement in a raytracer and due to the complexity involved to adapt it to a gpu raytracer i don't think any gpu based unbiased raytracer will support it propperly. we're hoping to implement this in the near future, but a pre-computed solution is planned for the near future (probably 2.3, catmull-clark subdivs and displacement, precomputed to triangle after loading from scenefile.)

is there no way to use the tessellation engine witch comes with new graphics cards ?

No, as this is a built in feature for a fixed function pipeline, eg DirectX and OpenGL,
and works with a zbuffer renderer like these cards do in hardware.

the tesselation engine is not available via cuda and is not easily implemented in a raytracer.
