Ribis - I've noticed the same thing, as well. Even in projects with very few objects on the screen at once. Switching to full-screen always affects the fps, but I'm not sure if it's something only C2 suffers from--it might be a general issue with games.
thanks for reply :)
I have always used Flash to create interactive sites with a very complex (all running in full screen without lag)
but it is very strange that with scirra this happens, because compared to action script html 5 is faster ...
is a real shame, I'm developing a 2D platformer with 14 layers that interact with each other, where I entered the wind that moves the physical objects ... etc objects between sprite, written etc. .. are about 100 and everything moves perfectly, 45/60 fps stable
I also integrated joipad for the movement of the player and everything works fine if it is not in full screen ... (700 x 500)
I also tried to disable all visual effects such as wind, smoke, dust particles carried by wind ... etc. .. and trying in full screen continues to lag ... I also tried to remove the layers leaving 7 ... just keep going shots ...
the game in full screen makes everything more effect ... in addition to being beautiful you are immersed in the game better ...
thank you very much
