Very interesting guys, thanks for your help, I too would gladly pay to have that Ludei logo removed, or just shortened so it only comes up for 1 or 2 seconds and that's it, just like some games put Havok physics logo before their games, it only displays for a very short time.
I have been able to add my own splash image before the Ludei logo is shown, but my splash is shown for a disproportionately short time in comparison.
However, performance wise on Android i still get highest FPS via cocoonJS, my game gets 58-60-fps, while my export via Intel IDX Crosswalk i only get about 45-fps average, I know it's still in Beta, but that's lowsy performance in comparison -> 25% worse!!
