Purpose and Scope
As of today, the gap between 1.5.97 and 1.6.x has widened. Most major modern mods (like Community Shaders, newer animation frameworks) have dropped 1.5.97 support entirely. While running the old USSEP on an old game is perfectly fine for a "frozen" load order, starting a new mod list from scratch on 1.5.97 is becoming increasingly difficult. skyrim se unofficial patch 1597 download new
