You are gonna to need Havok fix since the physics breaks at anything above 60fps, requires SKSE https://www.nexusmods.com/skyrim/mods/91598 https://www.nexusmods.com/skyrimspecialedition/mods/18160

just a warning, stuff like this happened in the past: https://www.vg247.com/2015/01/26/digital-copies-of-far-cry-4-are-being-deleted-from-uplay/ But I've also bought games from there. Hell, I bought the DLC for Skyrim since I didn't want to pay $60 later for a 64bit Skyrim with some texture mods Also, for a more legit site, there is sites like GreenManGaming. Also, heard good things about cdkeys.com but not sure.
