Hello !
I have some FPS trouble with the GrabPass System using distorsion with particles and Meshs.
I know there are different methods to fake distorsion, using a second camera or using Texture instead of Grabpass.
But my problem is different :
I used PS4 / Xbox / Switch and the grab pass FPS seems in trouble only on PS4 System.
FPS Low when Distorsion is active…
N Switch still ok ??? 
I dont really know if it’s come from Shader Settings or something…
If someone have the same or different trouble on some platforms maybe you can help me ? 
Thank you !
