Object.MergeIntoBackground performance query

[SSH]

Does merging an object into the background make the game run faster than if you have the object on with its baseline set to 0? I'm using lots of objects onscreen and objects 0 and 1 are backgrounds, really. Would merging them make the game run faster?

Well, the manual certainly hints at that...

Merges the object into the background scene for this room. By doing this, the object becomes part of the background and so does not slow the game down.

Ah, I knew I'd seen it somewhere. But if you have 18 objects going, does taking 2 out save much? Also, I think its easier just to keep them as objects. Ah well, we'll see if people have problems in beta.

If they are small, it won't make much difference.
If they are the size of the screen, it could make a significant difference.

Indeed. If you Merge them, then in performance terms it's as if they're not there at all. Try it and see.
