QtQuick 2 performance

gluck

Hi,

I am having big troubles with quick 2:

the pc i am running a program on is miniITX with intel atom dual core 1.8 GHz (4 threads), with 1.9 GB ram and with GMA 3150 integrated graphics. OS is Ubuntu 14.01 32bit.
the qml files are being loaded with QQuickView.

I think processor is more than enough, but performance with quick2 is really bad (huge latency).
And while testing with quick 1, there is no such problems, everything works good.

The main broblem is that i can't use quick 1 because there is no canvas support.

Does anyone have any ideas how to improve quick 2 performance, or knows a workaround for canvas element in quick 1?

This is probably about OpenGL. Make sure you are using drivers from Intel, not Mesa.

and is there a possibility, to render quick2 with raster surface (QBackingStore) and not with QOpenGLContext?

As far as I know, the answer is no. It needs to use OpenGL.
