about bloody time , good news indeed ,since  this engine is based on cycles , so iam assuming its gpu powered ? 

The GPU render doesn't support the full feature set the CPU render does. If we implement GPU support we end up limiting capabilities of the render. Things like limiting the number of texture maps in the scene. I'm with you on speed. I just don't want to sacrifice quality to get there.

truth is, GPU rendering is hardware challenging. If you don't have at least 2GB GPU RAM you will probably run into problems with lager scenes. but even then there are ways around it (like not using ridiculous 4K textures when you're only rendering at 2K) Octane for example comes with a script that lets you reduce the size on any textures in the scene. to disclaim an option just for some limiting factors is not a good choice, considering you still can fall back to CPU or even Firefly.

for those interested in render facts for cycles, have look here:
