currently using dx10 fixer version 1.4 How di I fix this shiny wing???

what settings would you suggest I change in DX10 fixer, besides this everything else working fine, with dx10 fixer.!!!

Try turning bloom off! Then turn it back on and try reducing reflective bloom slider and or alpha bloom. There is a possibility it's the environment reflection which these won't help with. I am looking at some issues like this for next release , there will be a glare slider.

turned bloom off and that seemed to work.
