Hi All,

I am facing issues in improving performance of Ping-pong mechanishm on adreno 330 devices.

Apple and Mali GPU has an extention of gl_ext_shader_framebuffer_fetch or similiar to get colors of last framebuffer and hence gets good performance. But i am unable to find any workarround in adreno GPU's. I have tried following methods

1. switching between FBO's.

2. attached 2 color attachments to a single FBO, used one as a source and other as destination alternatively.

Any kind of help aur guidance will be appreciated.
