Hi

 

I downloaded Qt5.4-beta and compiled in order to test the QtTestBrowser application with WebGL because it was performing awfully in Qt5.3.

I notice that with Qt5.4-beta it is getting slightly better with regards to CPU load but still it is a questionable performance !

 

I run some online webgl test like:

 

./QtTestBrowser -platform eglfs -graphicsbased -opengl-viewport -webgl -plugin evdevmouse:/dev/event1 http://ahoj.io/dart-webgl-simple-demo

 

and the CPU load is around 55% and I can see that the galcore daemon is around 1%.

 

Is there anybody that has some input on this ? Are those maybe expected results ? if so, what browser could perform better ?

 

regards

Einar
