How to validate performance of a robotic RL agent?

Hi all,

I designed a custom task using Isaac GYM with RL-Games library. I am not an expert of RL so I am assuming that the first way of validating the robot agent is physics simulation. Since my machine does not have a powerfull enough GPU to render all the physics simulation, I need an alternative way to validate the performance of my RL agent.

Can you give me some advice?

Thanks in advance!
