Performance/framerate issue

I was playing with a scene that had 1.3M tris, and getting terribly low framerates. I tried to see how things would be by eliminating things, and I eventually came upon a scene that was basically just the skybox. Still, my framerate is under 30fps. Any idea what might be causing the issue?

(Note: I don’t have a dedicated GPU, and that could be an issue. But still, I have got > 60fps before and this is just a plain scene with 48 tris, so there’s no reason for this to have such low framerate).

As the stats in the topright say, your game is busy doing things on the CPU. Probably scripts you’ve made.
