We managed to confirm that DirectX 11, the dominant API in computer graphics won't support ray trace rendering.

Microsoft doesn’t want to go down that path simply as the developers are not ready to give up a years of rasterisation experience.

A lot of industry people have expected that Microsoft will pull in a favour for Intel and include ray tracing in DirectX 11 specification, but we can now clearly say that this won’t happen. Larrabee, Intel’s mysterious discrete graphics project is supposed to be good with ray tracing but unless some developer does something in OpenGL there won’t be a 2009 chance for DirectX 11 based ray tracing game.

Nvidia and AMD(ATI) are continuing to make rasterisation chips and this looks to be the right way, at least for a few more years.
