OpenMW doesn't support Morrowind script extender version 2.1, he supports until version 2.0. But modders do scripted mod only for openmw (very equivalent to MWSE v2.1) Also OpenMW has post process shaders, same as MgeXE and Other which makes better graphics than original engine (In my video i don't have any post process) You should check Mr.Moonshine's OpenMW Video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HVUe0e78TzA.html
