"I think I found it! Chaos uses raycasting: link(https://youtu.be/Wc6lUXOhRO0?si=WS-fm32kZ7tv9ccx&t=317), and I think you can’t raycast with a GTX 1080 (I have almost the same PC as you), but you can with an RTX. I’ve tried to find a way to raycast with a GTX (some articles talk about it), but I’m not sure.
Thank you for your comment, it led me in the right direction."
