Troubleshooting

Are you having technical difficulties with Whispers of Prague? You might find the answer on this page. If not, feel free to write to us.

The game won’t start and displays some mysterious Vulkan error.

Whispers of Prague runs on Godot Engine version 4, which requires a graphics card with full support for Vulkan, a standardized system for high-performance graphics operations. It is possible that some older PC configurations do not support this system, and therefore the game will not run. However, Vulkan drivers exist for practically all newer graphics cards, so the simplest solution is usually to update the graphics card driver to the latest version.

The game crashes after displaying the splash screen.

This unusual behavior may occur if you are running Whispers of Prague from Steam and have an application installed that allows custom overlays in games, such as Overwolf. There are likely conflicts between this application and the Steam overlay. Try disabling the relevant application (Overwolf) and launching the game again.

The game still doesn’t start or suddenly crashes.

It’s likely a bug that we haven’t managed to uncover yet, or it’s related to a specific version of the game. Please send us the logs that the game creates in the directory C:/Users/<UserName>/AppData/Roaming/Whispers of Prague/logs (<UserName> is your specific directory in Windows), preferably via email to info@shadermess.com.

You can also check the Event Viewer in your Windows and examine any errors that occurred at the time of launching the game. In some cases, you may see errors containing a path similar to this.

C:\Users\Filip\AppData\Local\Overwolf\Extensions\ncfplpkmiejjaklknfnkgcpapnhkggmlcppckhcb\236.0.2\obs\data\obs-plugins\win-capture\ow-graphics-hook64.dll

If that is the case, the issue is related to the previous paragraph.

Another reason could be that the game is being blocked by an antivirus program for an unknown reason. Try temporarily disabling the program and running the game again. It may also help to add Whispers of Prague to the whitelist of the particular antivirus program.

The game is slow on my 4K display connected to an older laptop.

If you have encountered this problem, find the Stretch Mode option on the Settings screen (in-game) and switch the value to Viewport. While this mode may cause some graphical elements (such as text) to be rendered less smoothly, it will increase overall graphic performance.
