So I just noticed this VBO thing, and I think it could be the reason I can barely run my scene.
Here’s a screenshot
Why in the world is it so high if all I have is a terrain and some trees?
I had generated a RAIN navmesh but I deleted it.
You are also using pro water which uses another camera to generate the seas reflection, and therefore it will double the work of the GPU then factor in the scene and game view.
Notice the reflection main camera and scene camera.
But would it be that high just from the pro water?
Turn the water off, hide or close the scene view and try it again.
As it looks like you’re using the pro water you could also run the profiler to help you work out what is causing all the draw calls.
I have heard on the forums that there is a performance problem with trees, you could save the scene under a different name and erase the trees.
