Debugging QML and OpenGL performance issues



  • Hello,

    We are using MeeGo IVI ux http://meego.gitorious.org/meego-ivi-ux/meego-ux-ivi on Freescale iMX53 EVK and Sabre boards. On EVK we get decent performance with the ux and Qt hellogl_es2 example, 60-100 FPS using WGA (800x480) display. But on Sabre board using same kernel and userspace drivers and XGA (1024x768) display the FPS on hellogl_es2 drops to 2-8 FPS. If we change the framebuffer resolution to WGA (800x480) we get decent performance back. Also, if we run only hellogl_es2 and X without the IVI ux, then we also get the original 60 FPS with XGA resolution.

    Question is, how to debug this OpenGL ES2 related performance drop in QML applications?
