dv_, jnettlet, otavio, about Qt5 performance in imx6 (wandboard solo), I am able to lower the cpu usage by setting QSG_ANTIALIASING_METHOD=msaa
<jnettlet>
kroon, what does it use by default, vertex?
projectg1s is now known as projectgus
<kroon>
Also, playing with QSG_RENDERER_BATCH_VERTEX_THRESHOLD and QSG_RENDERER_BATCH_NODE_THRESHOLD I could drop the cpu usage from ~50% to ~10%
<kroon>
jnettlet, yes, "vertex" it seems
<jnettlet>
that seems like a very expensive default
<kroon>
I guess maybe Qt considers these parameters hardware vendor specific
<jnettlet>
it is actually up to how you setup your window. It looks like you need to set the samples property to the window and then QT will implement MSAA over Vertex
<jnettlet>
I guess that is my "learned something today" moment

kroon, you are going to write this all up on a "howto" wiki for the MX6 right? :-)
<kroon>
jnettlet, hehe.. well there ought to be one..
<kroon>
jnettlet, one idea for Yocto at least, would be to patch Qt5 to use "sane" default values, if we could agree upon those

jnettlet, I can't find that "samples" property you mentioned ..
