[Question] Try to use sbx on meltingpot env

[ZzzihaoGuo]

Hi,
I am trying to build a benchmark based on sbx on meltingpot envs. But I find something very wired. When I use the stablebaseline without jax, the fps of env slightly increase with the timesteps. But when I used sbx, the fps slightly decrease with the timesteps. Do you know why these situations happened? Thank you so much for your help.
