Hey folks, Getting into training with multiple simultaneous environments... Right now I have 8 environments going, and it's giving me a 2x speedup. CPU is at 15%, Memory at 40%, disk/network/gpu are all negligible. Any thoughts as to what's causing the bottleneck here? Also, below is a screenshot of the reward: Orange is 1 instance, blue is 8 instances. The problem is the same. Any clues as to why it's gone all... saw-tooth-y?
