Are graphics settings applied when launching through SKSE or Vortex?

[LanzeVanze]

Greetings everyone,
I'm currently at a dead end as I've been struggling with an issue for the past three days. That's why I'm calling for help from the wisest, most knowledgeable, and experienced inhabitants of Skyrim.

The Issue:

I've installed Skyrim Legendary Edition, SKSE, Vortex, and the following mods in this load order:

Skyrim.esm

Dawnguard.esm

HearthFires.esm

Dragonborn.esm

Unofficial Skyrim Legendary Edition Patch.esp

RAS - Riverwood CharGen.esp

Odin - Skyrim Magic

Overhaul.esp

Wintersun - Faiths of Skyrim.esp

random alternate start.esp

Apocalypse - The Spell Package.esp

Imperious - Races of Skyrim.esp

Summermyst - Enchantments of Skyrim.esp

Andromeda - Unique Standing Stones of Skyrim.esp SkyUI.esp

Ordinator - Perks of Skyrim.esp

Since my laptop isn't very powerful, I experience FPS drops in many locations in Skyrim, as well as the "flickering shadow grid" issue on stone surfaces (I know how to fix this via shadow settings). Because of this, I don't use ENB or any other graphical modifications.

After trying to make the game more comfortable by modifying the SkyrimPrefs.ini and Skyrim.ini files using Notepad++ (located in Docs/MyGames), these settings apply correctly when I launch the game via the standard SkyrimLauncher.exe. However, these settings are ignored when launching the game through Vortex or skse_loader.exe.

Despite clicking "Game Settings Files" in Vortex taking me to the Docs/MyGames directory, I strongly suspect that Vortex or SKSE has its own hidden configuration file, which overrides my settings and forces Ultra settings every time.

This is not a case of my personal files being overwritten, since my test setting of 800x600 resolution remains unchanged and only applies when launching via SkyrimLauncher.exe.

I also observed the same issue on my second laptop, suggesting that this problem is more widespread than it may seem...

I sincerely hope for your help and input, as I'm desperate.
Thank you!
