Camera renderer is horrendous

The renderering is horrendous in Unity editor,maybe there is a lot of ploygons in the game.But I am still wanderring whether there is some way to speed it up.. And when I compile the game and then run it,it is OK,at least about the fps. Is there any difference of the camera renderring or the data statistics between editor mode and the game mode?

 

You have 26K batches, that's a pretty big red flag. You'll need to reorganise the your assets so that:

1. Lots of objects are marked as static. This will allow Unity to group some of them together.
2. Lots of objects share the same material. This should allow Unity to group static objects better, but also amortise the cost of rendering the non-static ones (I might be wrong on that, maybe it's only in the scriptable render pipelines)

 

Above is the correct solution to your problem. Camera.Render is sending 25000 jobs to the GPU every frame.
Read up on reducing draw calls, for unity specifically and in general.
Static objects, shared materials and instancing are 3 major ways.
