Last relevant guide update: Hikari & Nozomi GL debut.

After the release of these banners, there weren't any major common problems at the same level of the ones listed here.

This is my first info-dump so expect a lot of bad formatting practices.

If you know another issue or a fix to a problem I haven't described here yet, let me know and I'll try to add it if there's enough info available.

Fixed (no discussions threads made these days compared to the release days and the game runs acceptable on hardware without Vulkan support).

Fixed and available in a patch note.

Somewhat fixed and available in a patch note.

(This workaround fixed the issue for me, maybe it'll help you too)

• Go to the game's folder (Right Click Blue Archive - Manage - Browse local files)
  
• Create a shortcut of the game's executable (Copy - Right click on File Explorer - Paste shortcut)
  
• Right click the shortcut - Properties
  
• Change "Run:" to "Minimized"
  
• (Optional, might help) go to the Compatibility tab and tick "Run as administrator" (this will make the game unstable and prone to crashes, enable only if nothing else worked) and "Disable fullscreen optimizations"
  
• Apply the changes and close the shortcut settings window
  
• Start the game from the shortcut (not Steam) and wait for the "Nexon Game Security" notification to appear

• When running as Administrator, Steam Overlay won't work and the game will complain about it, but you can play normally, assuming it didn't crash before.
  
• After the first succesful launch (you made it to your office or L2D), close the game and try reverting all the changes made one by one (launch the game after each change reverted) until you can launch the game directly from Steam without modifications and not vía the shortcut.

Install the VP9, AV1 codecs and WME (Windows)/Vorbis (Linux).


Using Microsoft Store:

AV1 codec[apps.microsoft.com] (optional?)
VP9 codec[apps.microsoft.com]
Web Media Extensions (WME)[apps.microsoft.com] (the game might have installed this one already)

Using Winget (Powershell) to install everything in one command (Unknown if the game needs those installed with or without admin privileges):


Use Winget only if you can't use MS Store.

• Add this to your launch options:

Follow this guide.

After activating some EX Skills, you might encounter graphical glitches such as distorted colors, heavy stutering, or flickering, it doesn't matter which one you get as they're part of the same issue.

Here's an example:
(Click here if you can't watch YouTube videos in Steam).


The game "fixes" it itself if you use these skills several times in the same session.

If you're running the game as an Administrator, switch to normal user and try to launch it again.
There's not a lot of info about this.

This warning appears when you run BA as an Administrator (maybe you had the black screen on launch issue).
You can ignore it if you want but it might crash the game in the future.

• Launch the game as a normal user (disable "Run as Administrator" in the Compatibility settings).

This will probably never become an official thing in the game but if you want to use a controller for some reason, here's a suggestion.
This section uses the DualSense (PS5) as a base.


You could use the gyro as mouse if you're experienced with it.
There's room for improvement but you can make your own configuration based on this if you ever feel like playing BA with a controller.

The buttons for the EX Skills were inspired from Yakuza 0-5.
The trigger to mouse clicks were taken from the vast majority of FPS games.

There's no in-game way to reduce the brightness, you'll have to lower your display's brightness settings.

Unlike the mobile release, this port has no way to change the resolution via normal means.

This is how it looks like in the mobile version:

Nonetheless, Unity allows custom resolution values using command line arguments.[www.pcgamingwiki.com]
This is an example of the game running at 640x480.


If you want to do this, you'll have to add the following commands to your launch options:

Change <width> and <height> to any desired value.



If the game launches in windowed mode and it crashes, add "-screen-fullscreen 1" so the game will start in fullscreen mode.

However, PCGamingWiki warns that using values that are above what the game can handle might cause visual glitches and broken menus.

Located in %localappdata%low\Nexon Games\Blue Archive.
DeviceOption is a text file whose purpose seems to be where the game saves some (mostly graphics and audio) settings.

If you changed some settings and the game crashes on launch, changing some values in this file back to the default values (or manually via "Reset Game Settings Info") should fix said crash.
Fixing this file is a better approach than deleting the entire Nexon Games folder as you're deleting lots of unrelated files.

To make the game generate a "clean" DeviceOption, you have to click on the "Menu" button in the Start screen (not your office/L2D) and then click "Reset Game Settings Info"... Or you can just delete the "old" DeviceOption.

There's not really much to do there other than simply looking at the recruitment videos without the UI, location backgrounds, time limited images/videos and so on.
Voicelines are in password-protected .zip files.

(You might be able to swap some assets or "add new" content[gamebanana.com] but there might be consequences, you've been warned).
