Right click the game, manage, browse local files
Go into the movies folder, delete everything.

This should remove the original NWN2 splash screen movies.

Search for a file named "ee_bootscreen.xml" you will find a few options. I am using english so for me its located in the following folder:
E:\SteamLibrary\steamapps\common\NWN2 Enhanced Edition\localization\english\ui\default\enhanced\bootscreen

It shouldn't be hard for you to find it for yourself.

Next just delete all the sequence panels!
If you don't want to, skip to the next section and just copy paste that into the .xml it should work fine.
Or alternatively download my mod from the workshop.

For example you will see:


Delete that entire block of code. And keep doing so until you are left with a text file that looks like the following:


You should have no more and no less in the file. Now whenever you boot the game it will not run the splash screens.

Copy paste this into the file if you don't want to delete things yourself:

<?xml version="1.0" encoding="utf-8"?>

<UIScene name="SCREEN_SEQURNCER" fullscreen="true" idleexpiretime="0.1" x='ALIGN_CENTER' y='ALIGN_CENTER' priority="SCENE_INGAME_FULLSCREEN" enhanced='true'/>

<!-- SEQUENCER_PANE - a panel containing panels for slides -->

</UIButton>

<!-- All panels that are contained inside the SEQUENCER_PANE and have the name SEQUENCER_PANE_(number) will be scrolled in the order of its number -->

</UIPane>
<UIIcon name="BG_BLACK" img="fx_white.tga" width='PARENT_WIDTH' height='PARENT_HEIGHT' color='000000'/>

If you don't want to touch the .xml at all, and don't want to mess with it every time there is an update you can download it from the workshop.

Unfortunately I can't do much about the movies, something is preventing me from even overriding it with 0.001 second clips. If anyone figures out a method let me know I'll have it added in.
