Memory and States.

Memory and States.
Inmediatly after calling SomeState.set(1.f); by first time, EE reserves 40Mg in RAM.

This happen before Shutdown of the current state is called and before Init of SomeState. So aren't my functions. This memory keeps in use all the time.

In my game, 61 mg goes to 97 mg. Obviously this is not viable for an iOS / Android game.

Why this memory is being reserved? How to avoid it?
Ok, I did found how to avoid it.

StateLogin.set(); or StateLogin.set(0.f); don't use fade effect and the 40 Mg aren't allocated...

But why?

RE: Memory and States.
there can be 1-3 render targets needed for fading effect.
memory usage depends on the screen resolution.
on mobile devices memory usage is smaller. the fading works ok on mobile's, I did test it for my sample project and it's okey.

Understood. I guess you didn't test it on iPad3. With a resolution of 2048x1536, fade effect allocates 40Mg on iOS.
And here is the prove:

12*3 = 36 mg.

I'm not trying to give you more work. I will not use fade effect , no prob.

(I've edited my previous post, on opengl there are up to 3 render targets used)
yes, that's expected, 2048width*1536height*4bytes*3rts=36MB, ipad3 has 1GB ram, so it's not an issue

Thanks, glad to see you don't forget things like this smile. It's important to keep an optimized memory usage.
