Today i noticed this warning inside Intel XDK
Warning: Crosswalk 7 uses an insecure version of OpenSSL and may be rejected by the Google Play Store. Use Crosswalk 10 if you plan to distribute via the Google Play Store.
But what i found is that Crosswalk version 10 has a dramatic effect on performance, the frame rate is about 8 fps !
With Crosswalk 7 Games run at average 45 fps.
Another strange thing I've found: Games with Webgl disabled (Canvas 2d) are much faster ! Webgl supposed to improve performance but i found Canvas is much faster!
I've no idea why, so please tell me what is happening.
