Hello, I have few questions about the decision requester. When I increase the period of decision in the RollerBall tutorial, it speeds up the game. Why is it happening ? I also wanted to know if a policy adjustment for a PPO trainer is what we call a decision taken by the agent. If we set the decision requester period to 1, a decision is going to be taken at each steps ? Does it mean the PPO policy is going to be updated at each step ? Or, is the PPO policy updated only at the end of an episode ? An other question : what is the duration of one step ? Does it depend on your CPU / GPU ? Thank you for your help !
