From scratch PPO RL training - Rainbow Road
I recently started working on training a model from scratch in my own bit identical physics engine of the game developed in Rust. It does about 5 million frames per seconds on GPU simulation where most time sadly still sits in emulating PowerPC instructions. Every realtime second it generates 1100 hours of gameplay which is used in the training/learning process and the result is beating all expert staff ghosts in about 15 mins of training. It is still quite some time away from even beating human world records, but soon it will be on that level. See here in this video the result on Rainbow Road.
