QOpenGLWidget Performance in IMX6

[vinodpillai]

I tried running a QOpenGLWidget sample in Freescale i.MX6 Quad/DualLite hardware and got an FPS of 29.

Link(sample): http://blog.qt.io/blog/2014/09/10/qt-weekly-19-qopenglwidget/

Same sample is supposed to run at 60 FPS on a i.MX6 SABRE Lite board

What all could be the possible reason i should dig into if i want to run it @ 60 FPS?

Hi Vinod

it may be recommended to use latest gpu libraries, look at latest

boundarydevices/linux-imx6 at imx_3.14.38_6qp_ga · GitHub

also 60fps may be problematic at high resolutions due to internal

buses bandwidth limitations.

Best regards

igor
