So, I'm done with testing! Some specs to consider: Windows 10 Pro CPU core i5-4690 | 8GB Ram GPU AMD R9 390 @1025/1500 | Crimson Driver 16.3.2 AMD Crimson "Power Efficiency = Off" won't work with applications run in administator mode. I used ClockBlocker instead! To keep the testing parcour as consistent as possible, I've decided to start a new game and use the Skyrim intro sequence until the first autosave (character creation) w/o moving the mouse/gamepad. I restarted the computer each time, before I ran a test! Vanilla Skyrim with only Update.esm, Dragonborn.esm, HeartFires.esm and Dawnguard.esm TES5 cleaned and ENBoost in the data directory

This means no DefaultHeapInitialAllocMB=768 and no ScrapHeapSizeMB=256. The Skyrim.ini and SkyrimPrefs.ini for Steam and Mod Organizer are exactly the same! https://dl.dropboxusercontent.com/u/8205360/Skyrim.ini https://dl.dropboxusercontent.com/u/8205360/SkyrimPrefs.iniLet's get startet: When I look at the graph below, I certainly can say that on my system Mod Organizer has a significant performance impact! I think this problem arrived with Windows 10 Pro! At first I thought it might have been the statistics tool I am using (Riva Tuner) - Fraps got the same frame drops nevertheless! My next try was the admin mode for Mod Organizer which operates quite well, but the Crimson Driver Power Efficiency @ off won't keep a constant 1025Mhz core clock (in graph equal to @ PE). What surprised me, was the weaker performance of a ClockBlocked 1025Mhz core speed! Even the frame times increased again (second picture)!
