small question about loading screen.

[certoipus]

I've search the forum for answer, but I don't exactly know what's the name of the option...

I mean there is a change in SS 6.3 or 6.4 that disables loading screen when you go back to game from other application or desktop. I would like to bring it back, 'cause it makes problems with my PC.
I remember it was a short solution for this issue, but can't find it
