Poor GPU performance in imx515

We are trying to use IMX515's GPU to perform some post-
processing of video streams. But the GPU seems to be too slow
for even just the simplest rendering task, for example just display
a 800x480 video frame on the screen. The rendering time per-frame is
about 60-70 ms that is to slow and will cause noticeable lag artifacts. Has any one done this before, fps rate under any benchmarks are appreciated.

For Nenamark, we get about 17-20 fps which is akin to others reports, but  isn't it too slow for a game or any meaningful 3D application?
