Project ENB says to change these settings:

bFloatPointRenderTarget=1
bDrawLandShadows=1
bTreesReceiveShadows=1
iBlurDeferredShadowMask=5 (if you use "Ultra" shadows)

But, the only one there is the first one: bFloatPointRenderTarget=0

None of the other are there.

Why?

Should I just add the rest manually?

Thanks! -oldplayer

There are game defaults which aren't in the ini files. I don't know about those specifically, but yes you can just add them manually.
