I am playing Zoo World on Facebook.

Initially, I had people walking in my zoo, and if I clicked on a tree, it shook in place.

I kept getting this pop up asking if I wanted to go to low quality mode? At least, that is what I think it said. Eventually, I clicked yes.

Now, the animations are all different. The people are gone. If I click on a tree, it pops up bottom center, in larger than life size, shakes, stops, go back to where it belongs.

So is there a way to go back to high quality?
Is the change only for that one app?
I wonder what I am missing in new games I add.

I have an HP PC, with Windows XP, if that is relevant.

Thanks for any ideas.
