Thank you very much, even though my problem has not been solved, hearing someone say it. To keep me from getting discouraged helps a lot, imagine that every game creator must go through small challenges. I think this is just one of many that I will and all of us as game creators will go through. I haven't found a solid solution for this, but I'm hopeful.
The content in the links are gameplays and videos. From my colleagues testing the game and showing me that the FPS on 3D maps is very low, from very small maps with nothing and no type of event on them to more complex events that are also low. My PC is very strong. So everything works very well on it, but on weaker P6s like on notebooks or even more precise ones. A little better ones also have cases of FPS drops on 3D maps.
