If your application runs on existing mobile devices with a software renderer, the application might not run well on a Mali GPU. This is because the optimizations for using a GPU can be very different to those for software renderers.
To obtain high performance with a GPU, your application might require re-optimization. In particular, ensure you do not use a large number of draw calls per frame. Batch objects together to reduce the number of draw calls.
For more information, see Minimize draw calls.
