Detached your post. It had nothing to do with the topic.
First off: stop this useless double/tripple posting.
We need more information to take care of your problem.
Post your system specs.
Have you tried lowering the settings, disabling or enabling OneTweak, disabling experimental multithreading etc.
Do you use any mods/ENBs?
Attach your LauncherLog:
C:\program files(x86)\Steam\steamapps\common\Skyrim\EnderalLauncher\system\log\Launcher.log
Upload a savegame.
Savegames can be found here: documents\mygames\skyrim\saves
A savegame consists of two files: one .skse and one .ess (please zip them together)
Thanks.
