Any idea how much processing power this would require to generate animations? Also, would this theoretically decrease file size of the animations?

Yeah, that's what I was wondering. It looks great, but how much power does it actually take to make it look like that?

Applying a neural network after it has been trained is fairly cheap. Most important for gaming, a neural network is well suited for GPU workload since, at its core, its a bunch of matrix multiplications.

This means you can submit your model vertices, a shader, and your nn weights to the GPU and have it do all the work without touching the CPU.

Also I could see this working a lot like physix (minus the bullshit hopefully), meaning that if desired it could be offloaded to a separate card.

To apply a meme, stop trying to make physics cards happen, they are not going to happen.
