Despite already adding all that
"<quality GameDepthOfField="0"
DepthDownsample="1"
CinematicDepthOfField="0"
FXAALevel="0"
CloudShadows="1"
MotionBlur="0"
id="medium" />"
to my GamerProfile my trees were always super aliased. So I set that to false, kept the above and now everything seems fairly smooth for an SMAA-antialiased image only.
