In short, I was a little bit bored, so I used an auto-clicker (set at one left mouse click by 1 millisecond) on a Construct 3 tutorial about artillery particles.
I don't know what kind of classified hardware the Construct 3 teams are using to provide us with this powerful and valuable game engine, but damn, this is a God-tier successful stress test here O.o
957130 objects (multiple sprites and particles) and I could still use the profiler (with 1 fps).
This game engine is way more powerful than I thought. I didn't screenshot it, but I reached over 1 million objects with still a functional profiler.
