I have noticed the same thing since I began my journey with construct 3.
According to my experience, switching ON all export parameters (image compression , no-reduplication, minification ) makes the game much more smoother (and exactly same feel which I get in a remote preview)
But unfortunately,I can't now switch ON advanced minification, because when I do so, my game hangs on loading bar. This is happening from that point when construct moved from Babel to Google spript minification
