[solved] QML Linux performance issues
I'm usually developing under Windows but of curse I wanna have system independent software.
From time to time I'm testing my software on my openSuse system to ensure that it still works.
A friend of mine said he tested a qml based project on his ... I guess it is a Linux Mint system
and told me that he has some serious performance problems with the qml UI.
To validate this I have tested it under my suse system and it definitely hase some problems.
I have a ListView in my UI which show image data and stuff I animate the hole thing.
I developed it on my windows 7 system on a pretty old machine with less performance.
And it runs pretty good now I've tested the same application on my linux system with
Intel Core 2 Quad which has a lot more power than my windows machine.
But the ListView itself and other animation run totally stuttering. It seems that the software
runs on a system that has to less performance to calculate the animations fluently.
Is this a known problem ?
Does anybody had made the same experience ?
What could cause this kind of issue ?
thanks for help
If you haven't seen it already, "this page":http://doc.qt.nokia.com/4.7/qdeclarativeperformance.html provides some hints for getting the best performance out of QML. Particularly important for X11 is the graphicssystem used: you will need to use "raster" rather than "native" for QML to perform acceptably ("raster" is default if you are using qmlviewer).
Hey guys, your are so great this actually solves the problem at the first sight.
before calling the QApplication constructor.
Now I get a pretty good performance on my Quad processor maybe I have validate this on
a weaker system, but I guess this should solve the performance problems we had.
Thanks mbrasser I already knew this page but I just forgot to consult this one ^^
