Yeah, this would be nice. I'd really like to be able to rely on Construct's in-built behaviors with out having to craft my own just to get around delta time. ;-;
I mean, it feels like the idea is that eventually computers will be fast enough that this won't matter, but right now I'm having trouble on a fairly fast computer whenever I try to stream or there are random FPS spikes / lags... and I can't even begin to imagine how awful it'd be on mobile platforms.
Once again, I totally respect where Ashley is coming from on this, but since we're not in the age of everyone-having-a-fast-computer, would be nice to have this as an option for devs like us who don't mind the FPS slow down and want consistent behavior.
