Looking at the picture you posted, you cloned something really bad. Most of the reasons must be that the number of clones is too many to cause the card.

Looking at your computer configuration, it's not bad , but it's not as good as my company's computer. I guess I can't preview the animation with that many clones. And yours is still a laptop. Mine is classed as a server machine.

So it shouldn't have nearly as much to do with the settings, and sometimes the software is set up so that it doesn't make much of a noticeable difference to the rendering.

With so many clones of your graph, it would be a lot of work to calculate the shading relationships between each object.

So try if you're stuck with fewer objects first 。。。。 If it's not stuck, it's just adding too many things.
