Crazy good results but without the paper (which the link at the time just goes back to the site) it's a bit difficult to check how good. What data is required, how long are training runs/how many steps?
It use neural network techniques, but it's not strictly using NN.
it do the same result as Nerf from google in 30min, nvidia result in 7minute. It can achieve more than 100fps if you let it train longer.
