Anyone has the same issue with me? Or am I missing something?
When using OpenGL version of Qt(not ANGLE version), as long as the application has constant animations or particle systems, it used 25% cpu on my machine. (one core)
Both Windows XP and Windows 7 has this problem.
tested Qt versions:
5.1.0 alpha, built with -opengl desktop
a dev branch checked out at March 23th, built with -opengl desktop
5.0.2 (downloaded at 2013-03-21-461, from http://download.qt-project.org/snapshots/qt/5.0/5.0.2/ , but it’s not there now) opengl version
A simple animation with ‘loops: Animation.Infinite’ reproduces the issue.
When I use ANGLE version of Qt (5.0.1), the simple animation uses cpu 0%.
I’m building 5.1.0 alpha without the option ‘-opengl desktop’ (i.e. ANGLE version). will post the result hours later.
