that is trained in the Arnon simulator itself so you don't need you don't need to simulate what things will look like rendering is often expensive computationally if you need to go all the way to rendering to train your policy I'll take a lot longer to do the same number of rollouts their oldest thing that low dimensional latent space to train the policy so it's called doom take cover here's a higher resolution version of what this looks like if you were to play this game yourself same approach laid out here again
