Assets Increasing Game performance or Fps rate

i have just worked with the environments like i wanted for my game but the problem is that the fps rate is very low 7-10 can someone please suggest me techniques to overcome this issue i.e how to increase the fps rate or performance of the game but still keeping the environments like the way they are ? thanks in advance

 

Different methods can be more useful or less useful, depending on how your scene is set up. When you have performance problems, it's always a good idea to use the profiler to find out exactly what is causing the slowdown.

 

- There are assets will turn objects far away to billboards
- Combining meshes
- When you have a terrain with grass increasing the value "Detail resolution per patch" can also help

 

+ LODs
+ Occlusion Culling
+ Lower Shadow Distance
+ Texture Atlases or Combined Materials
+ Minimise Shader Variants
+ Minimise Shadow Casters
+ Streaming
+ GPU Particles

 

thanks all
