Hear hear!
Construct 3's mobile department is hopeless, no one is even bothering to check for any issues.
It is pointless to argue since it's apparent that the Construct 3 developer isn't even aware of the issues or chooses to ignore them. So many people have tried and just gave up.
Most tests the Construct 3 developer makes are about how fast JS is in the web, since that's what he only ever truly does. And then advertise how fast JS is, and make it look like even mobile is as well. Not after those benchmark tests that have no relevancy to actual issues of performance stability and performance throttling on mobile builds.
For new users, if a game isn't as simple as Flappy bird or Angry Birds, then don't bother making it. If you think performance will get better after export, you'll be surprised it will be at least 30% worse after export than preview. And that's before the stability issues.
Back in 2016, the Construct 3 developer said devices are getting more powerful and the performance will get better. Well, that's true, but not that you will benefit from it, Construct 3 performance is getting worse.
Every tick needs to be light on mobile, but even the actual event sheet is so heavy and bloated, it's almost like a JS sandbox. I've fixed that by coding with JavaScript, but wait until you hear about a bigger problem, refresh rates on mobile.
The browser is still as slow, but the demand for graphics is getting higher. Dealing with 60Hz on mobile exports is bad enough, but now we have 120Hz, and the Construct 3 developer is acting like it's no big deal, they made another product Animate since they probably feel like they have so few things to improve in the actual game engine.
And then we suggest for frame rate locking, and the Construct 3 developer indirectly says it is a horrible idea for some technical reasons in which Chromium doesn't support, yet other engines like Phaser support. We then get linked to that everlasting Chromium issue that everyone already abandoned, forgotten or worked around.
What's worse, is that people who either are clueless or only exports to web, web mobile or desktop, will also reply and say that the performance is fine, making us getting ignored even further. That is until they have to experience it themselves, and then be the ones to complain in the future.
It's so easy to brush something off you don't experience or care.
