Game crashes caused by Razer SDK [Solved]


Recommended Posts

So before the last update, you could just shut down Razer Chroma SDK Service and you could run game without a single crash. But now, you have to enable it to run the game otherwise, your game will crash once Blade&Soul logo shows up. I figured out a way to solve this without a single crash.

Follow these few steps:

1. Keep 'Razer Chroma SDK Service' open

2. Log into game and start playing a bit

3. press CTRL + ALT + DEL and choose 'Task Manager'

4. In Processes choose 'Razer Chroma SDK Service' and shut it down

5. Go back to game and have fun :)


Once you shut down Razer Chroma SDK Service, your game might spikes a bit, try not to move while that happen and then it should be stable.

Here's my automated method...


  1. Open Notepad (Click Start -> Type notepad -> Press Enter)
  2. Paste the code in the quote below...
  3. Save as a BAT (File -> Save As... -> Choose location (I suggest Desktop) -> File name: BnSRazerLaunch.BAT -> Save as type: All Files (*.*))
  4. Run the BAT when you launch the game from now on.

@echo off
color 0b
title BnS Razer Temp Fix
REM Change BNSDIR to match your install directory.
set BNSDIR=%programfiles(x86)%\NCWest\NCLauncher
REM Do not change BNSVAR. It will be the same for everyone.
set BNSVAR=\NCLauncher.exe" /LauncherID:"NCWest" /CompanyID:"12" /GameID:"BnS" /LUpdateAddr:"updater.nclauncher.ncsoft.com"
goto precheck

REM This is to check for elevation. It's required for changing services.

Hi there.  I just installed this game and made it. . . not very far before I started encountering crashing issues.  After a bit it stopped launching all together.  I've done the fixes you've offered up but I still cant get it passed the logo that pops up right before I get a failure to launch notification.  Any ideas?

    Hello there,
    We apologize for the recent crash and disconnection issues you experienced after the maintenance. Rest assured we are working hard on a fix for these issues.
    In the meantime, you can try the suggested workaround posted in our knowledge base article about the recent crash and disconnection issues if you are using Razer peripherals:
    If the work-around above doesn’t work, you can also try uninstalling your Razer software and restarting your PC as a temporary solution. Our team is currently working closely with Razer on a solution for these issues.
    In addition, you can also check out to the following forum thread for potential fixes: https://forums.bladeandsoul.com/topic/162803-new-patch-supportfix-thread/?page=1Mark Yesterday at 21:22

    Thank you for the update.

    Unfortunately, optimization is still an on-going process. I am going to pass along this information to the development team so they are aware of the matter but for the time being, you may need to wait until those performance optimizations are released for this issue to be resolved.

    Our teams are actively posting in the following thread in regards to optimization as well as changes and updates, so I would highly encourage checking in to the thread every now and then for more information.

    This is where our departments go to collect the various issues and suggestions for the game.: Blade and Soul forums: https://forums.bladeandsoul.com/forums/

I wish... I'd love to work for NCSoft, but the stuff I know is way too limited. I'd bet they'd prefer programmers and translators.
