For performance issues and crashing problems, try the following

1. Run in compatibility mode for windows 7

Open up the game files on your computer. This is done by clicking the gear wheel on the game page, hovering over the "Manage" option and then clicking "Browse local files" in the popup that appears.


This should open a folder in file explorer that looks like this:


Once here, scroll down until you find "BLEACH_Rebirth_of_Souls.exe" and click it ONCE to highlight it and then right click to open an options menu. Click on properties (or press alt + enter) to open a new window.



Click the "Compatibility" tab at the top, you should see the following:



Click "Run this program in compatibility mode for:" for a dropdown menu, once here, click the option for Windows 7.



Also check off the "Run this program as administrator" option. Your compatibility window should look like this.



Once done, click "Apply" and close the window.

This is what helped me and my friends fix most performance issues, if anyone else has fixes, please leave them below and I will update this guide further.

1. Go to Windows Task Bar -> Settings -> Language and Region.
2. Change your Region to Japan, then — MOST IMPORTANT — change your system language to Japanese (this is your Windows system language, not the in-game language).
3. If you don’t have Japanese installed, click "Add language" and download it.
4. If when you hover your mouse over the time in the taskbar there are Japanese characters then you have succeeded.

Thank you to the amazing for this fix. Go check out his guide here!

Follow the steps in the previous section to find your games files and scroll down to locate the executable file for easy anticheat found in this folder (start_protected_game.exe):


Left click the executable file ONCE and right click it to bring up an options menu, once here, click on "Run this program as an administrator" and the problem should be fixed.

Alternatively:

Try lowering your sound format to DVD quality. sound control panel-> properties on the default sound device-> advanced tap-> default format. first try DVD quality and restart your game. if it works you can try higher quality until no longer works. (Thank you to Kachigga for the solution.)

1. Check your steam download region. This can be done by clicking the steam logo in the top left and clicking "Settings". Click "Downloads" and you should be able to see it at the top of the page.



2. If you and your friend use different servers (e.g: North america and Japan) you will have to match download servers before opening the game.

NOTE: Due to (what I think) is peer to peer connections, you will both lag no matter who switches regions.

Whether it be by helping out people by doing the steps in this guide for them, or by spreading word of this guide and sending it out, if this can help at least one person enjoy this game, then this has been a success.
