I'm speculating based on paper specs. It should be possible to keep the same level of physics simulation, as the XSS CPU still looks very powerful. Maybe graphics settings would need to be lowered, but I still have a lot of optimization work planned. My game doesn't use much memory (no textures, no open world streaming yet, instanced meshes), so I should be able to stick to the faster subset and the memory bandwidth there looks ok (8GB @ 224 GB/s).
EmberGen is really cool. I think we will be seeing it pop up in various games. There might not be volumetric export yet but people can still export image sequences. On their site they say Bluepoint is using their tools.
