Windows 10 and Intel stuck at initializing VFS

If you have Intel Graphics HD, Intel Graphics HD2500 and Intel Graphics HD4000, and are using the 64bit version of Firestorm 5.0.7 or later, on Windows 10, refer to this page.

Audio Issues After Update May 2018

A Windows 10 update in mid May has resulted in many having audio problems with the viewer. This is actually a problem with the update, and needs to be fixed externally to the viewer.

  • If your mic seems to have stopped working, try this: In your operating system, go to Settings → Privacy → Microphone and make sure “Allow apps to access my microphone” is ON.
  • In addition: A user has kindly provided this link to help you check your settings in the new Windows software and resolve the issue.
  • Further to this, you should also check Windows Mixer settings, since audio devices may have been reset.

Massive FPS Drop after Viewer Window Loses Focus

This issue is the result of recent updates of Win10, specifically KB3176938, KB3189866, KB3193494 and KB3194496.

Many users have reported that updating their graphics drivers has fixed the problem:

Should you not be able to upgrade the driver, read on.

  • To uninstall these Windows updates, go to Programs & features > view updates > click and uninstall. Please be advised that uninstalling any update marked as a security update is done at your own risk.
  • To keep windows from downloading the update again download this tool and run it to “hide” the update:
  • Note: “Hiding” one update will not prevent other, later updates. The FPS problem may return as other updates are installed and until Microsoft fixes this issue.

Please refer to this LL JIRA and this FS JIRA page for details and other suggestions.

Voice Is Distorted

If you suddenly sound like a man (and you aren't), or your friend suddenly sounds like a demon (and isn't), or you are hearing other forms of distorted voice, try this:

  1. Right click the Speakers icon on your system tray and select Recording Devices.
  2. Right click the Microphone and select Properties.
  3. Switch to the Advanced tab.
  4. Under Default Format drop down menu, select: 2 channel, 16 bit, 44100 Hz (CD quality).
  5. Untick “Enable Audio Enhancements”
  6. Press OK and OK.
  7. Relog if needed.

Sounds Don't Play

If you suddenly find that sounds do not play, things like button sounds or in-world object sounds, the possible cause is your default output format. Try this:

  1. Right click the Speakers icon on your Windows PC system tray and select Playback Devices.
  2. Right click the Speakers (or your chosen audio output) and select Properties.
  3. Switch to the Advanced tab.
  4. Under Default Format drop down menu, select: 16 bit, 44100 Hz (CD quality).
  5. Click Apply and OK.
  6. Relog if needed.

Missing Characters

If some characters now display as boxes, you will need to reinstall Windows font packs. Some of the more common font packs are Chinese, Japanese and Korean, though if you installed those and still see boxes, you will want to ask the person using those characters to tell you what language (or symbol set) they are so that you can install the appropriate font pack.

  1. Log out of Firestorm.
  2. Go to the Windows Start menu and choose Settings.
  3. In the window that opens, click in the search field at the top right and type in “language”
  4. Select Add a language from the search results.
  5. Click the + Add a language option and select the language from the list. The contents of the window scrolls left and right.
  6. Back in the Add a language section, click the newly added language and choose Options.
  7. Click the top Download button. The language will download and install, and it may take some time.
  8. Repeat this for each language pack you wish to install.
  9. Now log into Firestorm; you should see the missing characters correctly rendered.

Error 0xc000007b

Error 0xc000007b when launching 64 bit Firestorm:

Try following these steps to get the Firestorm installer to reinstall the Visual C++ redistributables that come packaged with it:

  1. First make sure you have the Firestorm installer handy in a place where you can easily access it when you get to the step where it's needed below. (You can download it from here, or from here if you need an older version than the current release.)
  2. Go to the Windows Start Menu and choose Settings.
  3. In the window that opens, click on “System Display, notifications, apps, power.”
  4. In the next window go down to “Apps & features.”
  5. Scroll down to the entry for “Microsoft Visual C++ 2010 x86 Redistributable.” Click on it and choose “Uninstall” (the list won't necessarily update to show that it is uninstalled, but it is).
  6. Click on “Microsoft Visual C++ 2010 x64 Redistributable” and once again choose “Uninstall.”
  7. Close that window.
  8. Re-run the Firstorm installer. The installer window will now say “Modify Setup” (since FS is already installed) and will give you 3 options: “Repair”, “Uninstall” and “Close.” Click on “Repair.” Firestorm will reinstall the Microsoft Visual C++ 2010 Redistributables that it ships with.
  9. Restart your computer. You should be able to launch Firestorm without getting the error message now.

Graphics Issues After Win10 Update

If you start experiencing graphics issues after a Win10 update, such as driver crashes, or simply very poor performance, the first thing to try is a full computer reboot.

If that doesn't help, reinstall your graphics card driver from the card maker's website, not from Windows. That is, from nVidia, AMD, or Intel.

If you have Intel HD graphics, refer to this page.

Camera Spinning or Mouse Wandering in Mouselook

The most common cause for this is a non-default DPI value, or screen scaling. Refer to this page for tips on setting DPI/scaling to default.

Unable to install current version of Quicktime

Some Windows 10 users have experienced difficulty installing current versions of Apple's Quicktime software on their systems. Version 7.7.6 of Quicktime has been confirmed to install correctly on Windows 10 systems. You can download version 7.7.6 from the link below:

Quicktime 7.7.6 (link will take you to the 7.7.6 download page on Apple's website)

**Unfortunately the above link seems to no longer be valid as a source for Quicktime 7.7.6, as such the recommended alternative to allow playback of media streams that were previously handled by Quicktime is to upgrade to a newer version of Firestorm (version or newer), as these newer versions of Firestorm no longer depend on Quicktime to handle stream playback.

Text and User Interface Too Small

First try increasing Preferences → User Interface → 2D Overlay → UI Scaling. Another possibility is Preferencess → User Interface → Font → Font size adjustment.

Viewer Window Larger Than Expected

This is most often caused by a high DPI scaling setting, usually 125% on most 2k displays. A viewer set to the same width as the display resolution (1920, for example), would extend beyond the display border. To correct this:

  • Log out of Firestorm
  • Right click the Firestorm shortcut and choose Properties
  • In Properties, click the Compatibility tab
  • Near the bottom, find and check “Disable display scaling on high DPI settings”
  • Click OK and Apply

When you launch Firestorm, it should display at the default DPI scale, 100%

Failed to Decode Login Credentials

Some Windows 10 updates change the machine ID used to create login credentials, resulting in Firestorm reporting “Failed to Decode Login Credentials”. The best way to deal with this is to wipe the stored credentials file, as explained here. Naturally, you will then have to retype the user name and password for all your accounts, when first logging in after deleting the credentials file.
