Impressive. But this is not proper way to go. Proper way is redesign of application to be not so memory hungry and GPU support. There are already World generating tools with GPU support, for example height map generation is 100x faster.
Which ones?
GPGPU is not the holy grail of everything, it’s not like you can stick 2TB of ram on a video card quite yet and i’m using big servers to generate very large (non tiled) areas as a lot of filters break down in quality on tiled (need neighbooring information they can’t get if it’s rendering elsewhere).
And WM is not “memory hungry”, it’s pretty good at what it does i’d say and the conserve memory that dumps intermediate results is a nice plus.
World-creator (former GEO control). Almost everything is realtime.
While that’s cool and practical, the quality can’t compare to what WM can produce. 
The workflow is also very different from WM.
I personally have a hard time using it for more than getting started on a shape, and always bring the produced shape into WM to refine and make the final product.
