Hello, I can run this opendev, but ...

As the game is very slow, i expect the issue is the coming from my PC, but can it come from anything else?

It's a potato, but it can run civilization 6 around 20 fps on late huge game, so I expected to run this opendev at a playable state...

The game look very cool, and I would like to test it and give a real feedback, but I can't
