Having issues? Check here for common issues and their fixes.

Installing

Installer does not open

  • Add an exception/exclusion in your antivirus and Windows Defender for the installer exe
  • Try installing the Microsoft x64 redistributable from here (don't forget to restart your PC)
  • Ensure you're running Windows 10 21H1 or newer. Project Duck and Microsoft do not support older operating systems
  • Restart your PC

Download is slow

  • Add an exception/exclusion in your antivirus and Windows Defender for the installer exe
  • Add an exception/exclusion in your antivirus and Windows Defender for the target installation folder (by default, %APPDATA%/ProjectDuckDN)
  • Disable realtime scanning in your antivirus and Windows Defender
  • Ensure you're installing the game onto an SSD. Hard drives are slow and will cause the installer to throttle speeds
  • Use a wired connection, not wifi/cellular
  • Maybe your internet just sucks (or sucks at connecting to Cloudflare's servers)

An error message popped up

  • Read the error message - it may tell you to do something to fix it
  • Post in the Discord with a screenshot of the error message and someone will help you

Crashes

Game does not start

  • Ensure you're running Windows 10 21H1 or newer. Project Duck and Microsoft do not support older operating systems
  • Check that your antivirus and Windows Defender have an exclusion for the installation directory, and that no game files were quarantined or removed. If they were, restore those files.
  • Restart your PC
  • Reinstall the game

Game window opens, then crashes

  • Ensure you're running Windows 10 21H1 or newer. Project Duck and Microsoft do not support older operating systems
  • Remove any mods you may have installed
  • Update your graphics/video drivers
  • If your computer is older, uses Intel graphics, or is running in MacOS or Linux, try disabling the Vulkan renderer via launcher settings (gear icon), Graphics, Disable Vulkan Renderer
  • Check that your antivirus and Windows Defender have an exclusion for the installation directory, and that no game files were quarantined or removed. If they were, restore those files.
  • Restart your PC
  • Reinstall the game

If you continue to have crashes, please upload your most recent ProjectDuck-DATE.dmp file to Discord and an explanation of when you crash.

Game crashes randomly

  • Remove any mods you may have installed
  • Check that your antivirus and Windows Defender have an exclusion for the installation directory, and that no game files were quarantined or removed. If they were, restore those files.
  • Random crashes are common with DragonNest in general, but if it happens repeatedly with the same situation or very frequently, please post in our Discord describing what you were doing. You should also provide any crash dump files you have (game folder, ProjectDuck-DATE_HERE.dmp) so that we can investigate
  • Restart your PC
  • Reinstall the game

Game crashes when I ALT-TAB

  • Use Borderless Windowed mode instead of Fullscreen
  • Disable Vulkan (see above)

Game freezes or Windows says the game is not responding

  • Do not ALT-TAB from the game while loading
  • Check your network connection, the game will freeze if it is unable to communicate with the server while transitioning between startup/login/town/field
  • Disable Windows' Fullscreen Optimization:

Game gives me an error message about an improperly named mod

  • If it is a mod you installed manually, give it a proper name in the form 00Resource_MODNAME.pak (mods installed via the launcher are already named properly)
  • If the name is Patch########.pak, your installation either hasn't finished patching, or you interrupted the patcher while it was patching. Delete the patch file and try again

Game gives me an error message similar to "you cannot modify X file with mods"

  • If it is a mod you installed manually, remove it - it contains files that you are not allowed to change using mods
  • If the file is a Resource## file, your installation is corrupt and needs to be repaired or reinstalled

Game gives me "Invalid Shader Data" error

  • Ensure your antivirus software didn't quarantine or remove any game files - restore them if it did
  • Repair your installation or reinstall if you cannot restore the removed files

Connection

My client freezes while loading and then errors with "Cannot connect to login"

  • Ensure your firewall or antivirus is not blocking the game
  • Ensure your internet connection is working
  • Is the server currently under maintenance? Check the #announcements channel in Discord for a maintenance announcement

I disconnect frequently

  • Use a wired connection, do not use wifi or cellular
  • Check that your internect connection is stable. Even small blips will cause disconnects
  • Check that your router and/or modem are not overheating. They should be warm to the touch, but not hot
  • Ensure your firewall or antivirus is not blocking the game
  • Check that your antivirus and Windows Defender have an exclusion for the installation directory
  • Users from certain areas of the world may not have stable connection to our server, which is located in eastern North America. You can try using a VPN or game network booster (e.g. Mudfish)
  • Your internet just sucks (or sucks at staying connected to our servers)
  • Use a relay server (launcher settings, Networking, Relay)

I received a "Dual Login" error

  • Try logging in again. This error usually resolves itself
  • Try waiting 10 minutes and try again. If you're unable to log in after 10 minutes, please ask for help in Discord

My attack damage comes in "bursts"

  • This is a DragonNest bug
  • Restart your client

Performance

My FPS is low

  • DragonNest is a poorly optimized game. Most PCs will not be able to run the game at high FPS especially in raids
  • By default, Project Duck uses an experimental renderer to improve performance, but it may not be compatible with all PCs (especially older ones). If your PC is not compatible with the experimental renderer, consider upgrading to a modern PC
  • Check that your antivirus and Windows Defender have an exclusion for the installation directory
  • Set Party FX Transparency to 10 in System Settings, you can also optionally set your own to 10 as well
  • Close other programs while playing
  • Check your PC's power performance settings
  • Use windowed or borderless windowed mode, not fullscreen
  • Decrease the game resolution
  • Turn off Vertical Sync
  • Adjust your graphics driver settings for the game to performance
  • Reduce the Quality and Effect settings to Low
  • Do not change the Texture Quality to Low, keep it at High
  • Use effect reduction mods
  • Restart your PC
  • Buy/build a better PC

My FPS drops when I unlock my mouse cursor and move it around

This issue has been mostly mitigated by a recent change. Please let us know in Discord if you still encounter this issue
  • This is a bug with Windows and many games, it's just worse with DragonNest because of its general poor performance
  • Reduce your mouse's polling rate (Hz) in your mouse driver
  • Move your mouse more slowly
  • Restart your PC regularly

Loading is slow

  • Ensure the game is installed to an SSD, not a hard drive
  • Buy a better SSD
  • Check that your antivirus and Windows Defender have an exclusion for the installation directory
  • Do not ALT-TAB out of the game while it is loading
  • Restart your PC

Misc

I disconnect when trying to equip or unequip a dragon gem

If the equipment you're trying to add/remove the gem from has a Skill Gem slotted, remove the skill gem.

I get "Invalid Request" when learning certain skills

You need to force reset your skill build via the website. Go to your profile page (link) (you may need to log in), select your character, select "Skill Tree", switch to the affected page (primary/secondary), scroll to the bottom, and press "Force Reset"

My mouse cursor is offset

This happens if you're in windowed mode but not borderless when your resolution is the same as your monitor's resolution. Turn on Borderless in the launcher > Cog Icon > Graphics

64-bit client specific

Application Error: The application was unable to start correctly

Your computer is missing certain components that are required to play. In PDLauncher, hit the settings button (top right, gear icon), press "Repair Client", and then press "Install Prerequisites". The launcher will install those components for you and then relaunch.

If you still encounter the error after installing prerequisites, you may need to update your DirectX

Water renders on top of other things

Go to your graphics driver's settings page (e.g. Nvidia control panel), select ProjectDuck_x64.exe, and disable antialiasing. The game has its own antialiasing and the driver one interferes with water rendering
