Thanks for the guide and response. Can you let know about how can I enable hardware acceleration in my application in yocto dizzy?

When using QT5 + eglfs: i. Frame rate is around 56fps with 800*480 resolution display. ii.Frame rate is around 23fps with 1280 *720 resolution display. iii.Frame rate is around 11fps with 1920*1080 resolution display. iv.CPU usage for above three cases is 99%. it seems there is no h/w acceleration enabled here. You need to figure out why When using OpenGL: i. Frame rate is around 56fps with 800480 1280720 and 1920*1080 resolutions. ii.CPU usage slightly increases with resolution from around 10% to 18%. Whats affecting Frame rate in QT5 and how can I increase the frame rate and improve CPU performance. I'm new to QT as well as image processing. Kindly let me know your thoughts on this to solve. Its a question better suited for qt mailing lists. There are several optimizations that can affect this but you have to know your load. Thanks in advance.
