Need help blending layers at high frame rates

We want to use i.MX 6Dual to drive a 1920x720 display with 4 blended overlays with at least one running at 60fps.  In our tests, on i.MX 6Quad SABRE Lite, we have not been able to achieve this.  We seem to be hitting a bandwidth limit and causing the system to become unstable, but it could just be that we have not configured the IPU/GPU devices correctly.  We are using an RTOS and configuring the IPU and GC320 to do the work.

 

Are there any good resources that explain how to use the i.MX6 graphics devices to achieve high frame-rate, high resolution, multi-layered graphics?
