After the collision detection is turned on, the FPS on the PC side is only about 30 frames, and on the mobile side, it is only about 6 frames. Is there any suggestion for optimization?

Do you run the provided example or your own one?
For me, this example works about 60 fps on my laptop and mobile.

I directly access the example address you sent, and it is a black screen after clicking to open through WeChat

It may be that the number of objects detected by the raycaster is large. I printed the timestamp log on the mobile terminal and found that it took 60ms.

If you have numerous objects in the scene, then yes, that might slow down the collision detection.
