Kernel version = is 3.10.17, Wayland 1.5.0, Qt 5.3.2. Branches: meta-fsl-arm: dizzy, meta-qt= 5: dizzy. I use LCD8000-97C display (1024x768) on LVDS output. Here are the performances I reach: - with eglfs (using option "-platform eglfs"): Performances are quite ok, from 48 FPS with graphical effects to 75 FPS whe= n all effects are disabled.=20 - with Wayland (using option "-platform wayland-egl"): Performances are really bad. Application is slow and FPS are wrong (always = displaying 62 FPS, definitely wrong...). =20 I know some others faced the same issue (https://community.freescale.com/th= read/333193, or opposite issue: https://www.marshut.net/iyismy/performance-= of-platform-wayland-vs-eglfs.html).=20 If anyone made a similar test, it could be interesting to share the perform= ance you got.=20 I was also wondering if it is possible to get any debug information from vi= vante gpu driver.=20 Regards, Vincent Cesson - Open Wide Ing=C3=A9nierie http://ingenierie.openwide.fr
