Quick2 has a slower perfomance when starting a qml Application compared With mac and Linux

[itviewer]

I described it in "http://qt-project.org/forums/viewthread/23987/":http://qt-project.org/forums/viewthread/23987/

bq. With my computer ，when start a Quick1.1 application（Official example），QDeclarativeView’s Window and qml contents are almost simultaneously displayed，while when start a Quick2.0 application（the same Official example），QQuickView’s Window will displayed faster than qml contents，it takes some time rendering until qml contents displayed。

I test it again With both mac osx 、kubuntu and Windows7，i fond that it only appeared on Windows，does it the reason that Quick2 use ANGLE replace OpenGL？ and i wonder if you have the same appearance on Windows？

if I want the same effect With mac and Linux，does that mean i have to compiling Qt5 by myself，and configure flag with "-opengl desktop"？ while I think that has a difficult for me……
