Render texture lag

I am rendering a texture from a camera during runtime(specifically,the mirrorreflection4 script),creating a realtime mirror reflection.Everything works fine,on the editor,but in out of the two of the android devices which i tested on,the one with a powervrsgx540 gpu delivers the desired results,but on the other device using the mali400,there seems as if the reflection(rendered texture) lags by a frame or so,the(reflection) follows the real object like a trail,when the character(main camera)moves.

Is this a known limitation of the gpu,or is there something wrong i’m doing,like not using the reflection probes instead(both of the listed gpu’s are old though).

Sorry but if your GPU are old, renderTexture takes a lot of performance. You render one more time by renderTexture.

You can reduce the size of your renderTexture to reduce the lag.
