Hi I've built freescale community bsp dizzy for a custom imx6q based board, and now I'm experimenting with GPU performance under Qt5.
I have both xcb and eglfs backends running (under different builds). However performance is lower than was expected: on LVDS 1280x800, Qt5_CinematicExperience shows about 35-37 FPS, both under X11 and under eglfs. If using smaller window under X11, FPS increases, if using 1920x1080 it goes down to 20. This is much smaller than people get [1]. [1] https://community.freescale.com/thread/305066 CPU in both cases (x11 and egl) is almost unloaded (30% of one core under eglfs, 30+30 under X11) so looks like speed limiting comes from GPU. What could be reason for this? Any hints?
