Folks, I need some help how to draw a huge and dense forest on my large terrain. It requires over 1 million trees but FPS drops to 5-10 even with 400 000. I am looking for effective tools or tricks, any advice will be appreciated. The player will go there so cannot be completely replaced with forest textures.

Welcome to this forum!!

Try to add fog and 5km of camera visibility.
-
Use tree game object with LOD.
-
Try to use a very simple shader for distant trees without a bump mapping, reflection, metallic maps, ambient occlusion, etc…
-
Add vertex ambient occlusion shadow to the mesh triangles.
-
Make the shader material that do not cast or receive shadows.
-
Do a unique custom simple transparent mesh that does not render but cast a shadow. face it looking the sun. Place this game object in each tree LOD. So that shadow is visible if close.
