Ability to tone down backdrops in options

I guess this is the main issue here, lower end graphic card holder are having issues with animated water.

Fast graphics actually stop animation for water entity but never backdrops.

So here is the deal, either make an option to respect the fast graphics rule or to let user turn it off to save them trouble rendering so much thing in the background and eventually crashes.

The backdrops are rendered by a special shader that renders with a single GPU call per backdrop geometry, but it tells the GPU to fill the geometry with duplicates of the texture instead of stretching the texture to fill the geometry.
This is also a built-in feature of the GPU, so it should be pretty fast.
In the end, a backdrop should consume as much GPU power as any other single entity in the game, if not less, as it is only two vertices.
