SureAI

Tried kind of everything I could.

-I don't have Skyrim installed, but I did try installing both the normal version and the Legendary just in case it could help, uninstalling them, erasing their my games folders, and etc.
-I tried multiple directories for the installation of Enderal.
-I marked the folders as "ignore" for my antivirus, and also stopped the antivirus while I tried the solutions.
-I tried all the combinations of desactivating/Activating ENboost and etc.
-Tried changing my resolution to custom, widescreen and etc.
-Disabling FXAA
-Disabling Anti Aliasing.
-My computer is perfectly capable of running Crysis 3, The Witcher 3, and even the infamous ARK/Atlas on max settings. GTX 1080 and i5-9th gen. 16 gigs of RAM memory and tried using both my SSD and my HDD just in case it could be doing something.
-Tried reinstalling
-Tried giving all the .exe administrator privileges.
-Probably more things because I have 14 hours of playtime and haven't gone past "New Game", so you can just imagine.
-I also don't have any mods installed.

please delete the 2 -.ini files under: C:\Users\...\Documents\my games\Enderal (Enderal.ini; EnderalPrefs.ini)
these are recreated at the next launcher start

That actually worked like a charm.

Please do kinly proceed to marry me for being so awesome.

No, really, thanks a lot.
