I don't know what got into me to do this but i dit it:
Originally i just wanted to test how many objects i can spawn before the framerate goes down.
The results where suprisingly interesting.
I limited the max objects by frame rate. i am pretty sure this could be usefull for other games as one could despawn objects if framerate drops. so the game will run good at maximum effects on each pc...
Objects before performance drops:
i5 2500k Chrome ~430
i5 2500k Chrome Canary ~1300
i5 2500k Firefox ~1300
i5 2500k IE ~360
XperiaZ1 Chrome ~215
Also interesting, if you despawn objects, even if you restart the layout, the engine can handle less than the first time.
Still pretty amazing what construct can handle these days!
Just wanted to leave this here as it might be of interest for some one
