OverviewV-Play 2 Support (Qt 5)performance › Reply To: performance




I’ve did some more investigations. It seems that performance impact is the rotating of the image within entity.

So, I’ve created simple pure QML Quick2 test with rotating stars:

import QtQuick 2.2
import QtQuick.Window 2.1

Window {
    visible: true
    width: 480
    height: 320
    Grid {
        anchors.fill: parent
        Repeater {
            model: 100
            delegate:     Image {
                id: sprite
                source: "rotaring_star_solid.png"
                width: 32
                height: 32

                RotationAnimation on rotation {
                    from: 0; to: 360;
                    direction: RotationAnimation.Clockwise
                    duration: 1000
                    loops: Animation.Infinite
                    running: true

here is 100 rotating stars, which takes only 15-20% of CPU


Probably this will give you some hints where the problem may be
