Those links really suck....
Each time I click on them a video file launches of an advertisement...
How rude....
Please find another way to share pics....

Now, about the fps problem....
You have a definite problem...
I do not see hardly anything in your level...
You should get a very high frame rate...

So, you need to figure out what is dragging down the fps...
First, you should look at each entity individually that is in the level...

That avatar....
What is it? File type?
What file type texture and how big?
Is it animated? If so, how? Vertice or bones?

You might try removing each component and switch it out with a different file which can help you diagnose the issues...

Next, could it be a code/script problem?
If so, seek more advice...
But first, check out each component of the level... Then go from there...

You might even try doing a "Save-As" of a different project and add your entity files to see what happens...

Best of luck...
