Start using LODs, and culling there you get many fps back, also using lower textures is a good way.

hope that helps :).

Hi krdmnmsh,

To add to siegencorgie’s answer. You can also use Level Streaming. It’s a great way to load assets only to the part of the level you are in. Here is some more info on LOD’s, Culling, and Level Streaming.
