Depth of field performance

[samuelcelko]

Hey there, been wondering if anyone else has had performance issues after applying depth of field to a scene. Code below.

<DepthOfField focusDistance={0} focalLength={0.015} bokehScale={1} height={900} />

FPS just tanks after putting this in. Tried to mess with the settings but nothing seems to be helping.
Does anyone have any suggestions on how to make the performance better?

Thanks!

Did you try to use DOF directly from postporcessing?

also did FPS drop in react dev mode or in prod?

in dev it might re-apply the same effect so you have multiple DOFs so that's why FPS might drop

I think this would be problem
DepthOfField.tsx in line 23
https://github.com/pmndrs/react-postprocessing/blob/master/src/effects/DepthOfField.tsx

every props or camera changes, DepthOfEffect instance has created in useMemo
so it causes memory leak
