Adding too many gameObjects to scene ruining performance.

Hey everybody,
So Im having an issue adding about 1000 trees to my scene. I downloaded these trees from the asset store and added about 1000 to my scene. It played fine in game mode but when i played in on my old PC it was no good even with the performance object “fastest” selected. The game works fine without them. Is their anyway to just let the game load for a while or do i have Instantiate them around my character?

I don’t think a question remains - per the title, adding too many gameObjects to scene is ruining your performance. If your trees are 4k verts and you add 1000, that 4,000,000 verts on trees alone and your old PC cant handle the runtime. Therefore, add less, optimize, etc there are many posts, articles, vid/tuts, on performance optimizations
