Is this because my mobile game has too much going onand needs to be optimized or is the previewer always like this? I can test on mobile over wifi directly from Construct 2 and it plays smooth, but on Intel XDK its very laggy.
Oh yeah one more thing with Intel XDK. How do I remove the black border around the entire game? It appears to be minimizing the game more than necessary even though there is plenty of real estate left.
Edit: I just checked the frame rate and here's what I got:
60 fps Construct 2 Mobile and Web preview
10 fps Mobile Intel XDK
32 fps Desktop Intel XDK
