EECH seems to be working okay for me, with the exception of enabling anti-aliasing.

I have a Nvidia 8800GTS-512.

ini settings are:

cbar=1000
fs=1
mfr=60
32bit=1
nrt=0
notnl=1
nodx9zbufferfix=0
3dreset=0
dxtm=0
cg=0
palette=1
eofullrange=0
render-tree-shadows=1

I have forced various levels of AA through nHancer. I have also tried various compatibility settings but haven't had any success.

Any tips?

(Edit: Oh, and I'm using the v1.12 community patch)
