Scene runs at low fps at just 90K Tris

I just built lighting for my scene using the Shadowmask mode. Now all my shadows are baked and the tris just got down from 1.1M to 90K.

The most strange thing is that the game was running at 60 FPS on my pc when the tris was 1.1M, and now it is 20FPS at 90K Tris. Why this?

I feel this as a glitch as when I played the game first time on editor, it ran on 75 FPS, but when I played second time it fell to 20 FPS.

How to fix this? I also analyzed the game on profiler, the result says that the Camera.Render is the most consuming task. But why so low fps on just 90K Tris? Pls help!

 

Okay. That might be what is causing it. Play around with the camera settings/render settings, and see what is causing it. It is also possible, that there is a problem, in your script too.
