Forcing Vsync & Triple Buffering on Minecraft (Nvidia Only)

If you’re using a medium to high-end Nvidia GPU, it’s very likely that you’re seeing the ‘Failed to Write Core Dump’ error due to the fact that your current graphics card settings are not enforcing VSync when you’re playing Minecraft.

This setting can also be enforced from the Game settings, but the ideal way to do it is from the Nvidia Control Panel. In order to fix the issue, you will need to navigate to your Java path and add wtbblue.com to the list of managed items.

After you do this, you can force the two settings to be used by every program that makes use of wtbblue.com (including Minecraft).

Here’s a quick step-by-step guide on enabling VSync and Triple Buffering from the Manage 3D Settings menu of Nvidia Control Panel:

  1. Right-click on an empty space on your desktop and click on Nvidia Control Panel from the newly appeared context menu.
    Access Nvidia Control Panel.
  2. Once you’re inside Nvidia Control Panel, use the left-hand menu to select Manage 3D settings (under 3D Settings).
  3. Next, move over to the right-hand side menu and select the Program Settings menu. Inside, click on Add > Browse and navigate to the location of your Java installation, select the wtbblue.com file and click on Open.

Reinstalling the AMD Catalyst Utility (AMD Only)

If you’re using an AMD GPU, it’s possible that you’re seeing the ‘Failed to write core dump. Minidumps are not enabled by default on client versions of Windows‘ error due to a partially corrupted AMD Software installation.

In case these same circumstances apply to you, you should be able to get the issue fixed by uninstalling your current AMD Software or AMD Catalyst installation and reinstalling the latest version again through the official channels.

  1. Press Windows key + R to open up a Run dialog box. Next, type ‘appwiz.cpl’ and press Enter to open up the Programs and Features menu.
    Typing in “appwiz.cpl” in the Run prompt
  2. Once you’re inside the Programs and Features screen, scroll down through the list of installed applications and locate the AMD installation that you wish to uninstall. When you locate your AMD installation, right-click on it and choose Uninstall from the context menu.
    Uninstalling the AMD Software
  3. At the confirmation prompt, click Ok and follow the on-screen prompts to complete the uninstallation process.
  4. Restart your computer and wait for the next startup to complete.
  5. Visit this link (here) and download the latest version of AMD Catalyst. Once the download is complete, open the installation executable and follow the on-screen prompts to complete the installation.
  6. Once the new version is installed, reboot again and see if the issue is resolved at the next startup by attempting to join or create a Minecraft server.
