Enb Binary 0.343SE with Rudy ENB Dolomite Preset
So far I found,
a. turn off swing effect of Ultimate Combat fix this, yes it's the main problem.
b. useOriginalObjectProcess=1 in enbseries also fix it. but will make Rudy preset unfunctional.
c. switch back to enb binary 0.341 with older version preset fix it.
Since these mods I use and Rudy enb are recently most popular ones in Skyrim SE, maybe there are other people meet the same problem.
