QOpenGLWidget Performance in IMX6

vinodpillai — Wed, 09 Dec 2015 06:17:47 GMT

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

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

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

buses bandwidth limitations.

Best regards

igor
