Hi
Thank you very much for your help. It has been very useful for me.
I thing I still need to learn many many more things about Unreal. Step by step, with the available tools, a lot of patience, I think I’ll be able to achieve a good performance in my game.
A thousand million thanks!
I found this video on YouTube… I think it’s a great introductory explanation for anyone who has no idea about optimization (like me). 
I’m leaving it here so people reading this thread in the future can see it.
