Thank you! That is what I needed.
@pandamicro @slackmoehrle I have deactivated Antialias (i can clearly see it in my screen…) and performance had a small improvement. I mean, from 30 fs to 40, but I see artifacts on screen. So, this confirms there are performance issues on web for 1.7-1.8 and I dont think they are related to Antialias.
I can see the low performance when I execute my game at the “default” size: 1334x750 (On Chrome, select default from drop down list). Works fine (50-60fps) with iPhone/ipad sizes. This is not happening with 1.5.2
