How to Fix Lost Ark Stuttering and FPS Drops

How to Fix Lost Ark Stuttering and FPS Drops on Windows 11

Lost Ark is an MMOARPG that runs on Unreal Engine 3. However, many users report stuttering and FPS drops while playing Lost Ark. If you're experiencing this issue, this article will help you fix them.

Lost Ark Stuttering

Game stuttering is irregular delays between frames that can hurt gameplay. While stuttering can occur in single-player and multiplayer games, this issue has a much more negative impact on multiplayer games.

Why Is Lost Ark Stuttering?

The stuttering issue is related to FPS drops. Our research has revealed that stuttering and FPS drops in Lost Ark can occur due to 1) computer data processing performance and 2) game data transmission speed.

  • Computer data processing performance. This includes system hardware configuration and optimal game settings. If your PC can't handle the data it needs to process, you will experience stuttering. Check if your computer meets the minimum system requirements.
  • Data transmission speed. Insufficient game data processing speed noticeably affects Lost Ark. Insufficient transmission speed can be caused by a congested network, wireless connection, bandwidth, and server.

In addition, you may experience stuttering and FPS drops by bugs or corrupted Lost Ark game files.

Before trying any of our fixes, here are some tips:

  • Turn off tab notifications for all chat windows. However, you might fix the issue by disabling only the Area chat.
  • Prioritize Performance over Quality in Lost Ark's video settings.
  • Set the Run the game in Borderless mode in video settings.
  • Set Lost Ark's framerate to match your monitor's refresh rate.
  • Disable overlays like Steam, Discord, Xbox Game Bar, Nvidia GeForce Experience, or Riva Tuner.
  • Update your graphics card driver.
