Optimize Lost Ark to increase FPS and get rid of stuttering.

Is your high-end PC struggling to deliver a smooth Lost Ark experience? You’re not alone. FPS drops, stuttering, and performance issues are plaguing even the most powerful rigs, leaving players frustrated and unable to fully enjoy the game.

Whether you’re battling hordes of demons or exploring vibrant landscapes, these sudden dips in performance can be game-breaking.

But don’t despair! We’ve compiled the most effective fixes to help you reclaim those lost frames and conquer Arkesia with silky-smooth gameplay.

How To Fix Lost Ark FPS Drop and Stuttering Issues

If you are also looking for a solution to fix FPS and stuttering on Reddit then apply the below-mentioned fixes.

Change Launch Options

Modify Lost Ark launch options through Steam for potential performance improvements. Follow these steps:

  1. Right-click Lost Ark in your Steam library.
  2. Select “Properties” and click “Set Launch Options.”
  3. Add specific options like -novsync, -notexturestreaming, and -useallavailablecores.
  4. Save changes and launch the game.

Mouse Polling Rate Adjustment

Users encountering stuttering issues in Lost Ark reported success by adjusting their mouse polling rate. Lowering it from 1000 to 125 resolved the problem for some players.

To implement this solution, access your mouse settings, typically found in the device settings on your computer, and adjust the polling rate accordingly.

Update graphics driver

The outdated graphics drivers are the core reason you can’t get 60-100 FPS. The GPU drivers affect the game performance and if they aren’t updated they lead to FPS drops, lagging, and performance issues. You need to update graphics drivers on your PC and laptop to optimize Lost Ark FPS.

There are two methods to update graphics drivers manual and automatic.

We strongly recommend you use automatic methods as it is more feasible and saves you time. Especially if you don’t have the skills to manually update GPU drivers, you need to download Driver Easy.

The Driver Easy is a software updater tool for Windows PCs. This tool automatically scans and updates drivers on a PC with just a single click.

So download the Driver Easy Trial Version on your PC, install and test it.

Graphic Settings Optimization

Experiment with different graphic settings within Lost Ark. Players have found success in improving FPS by switching between low and very high settings. Navigate to the in-game graphic settings and modify them based on your system’s capabilities and performance requirements.

  1. From the in-game play screen, select the Esc button.
  2. Within the Game Menu, select Settings, and then Video.
  3. Scroll down and select Auto Settings.
  4. Resume gameplay to test the change.
  5. If lag isn’t improved, select All and lower the settings until gameplay improves.

Full-Screen Mode Usage

Switching to full-screen mode, as opposed to borderless, has reportedly resolved FPS issues for certain players. To make this change, access the game settings and switch the display mode to full screen.

Disable Overlays

Overlays, such as Nvidia FPS and Discord overlays, may contribute to FPS drops. Turn off all overlays in your gaming and streaming applications to see if this resolves the performance issues.

Turn off firewall

Sometimes Windows firewall considers certain game files as a threat preventing them from running properly. If you are also dealing with the Lost Ark FPS drop then try adding the game .exe file in the firewall exception list.

Follow these steps:

  • Press Windows + R to type firewall.cpl and then press Enter.
  • From the left side click Allow an app or feature through Windows Defender Firewall.
  • Click Change settings.
  • Look for the game in the list of allowed apps and features while making sure that Private and Public checkmarks are checked.
  • In case the game file is missing, click Allow another app…, select LostArkLauncher.exe, and then click Add.
  • Once you’ve done that, make sure that LostArk has checkmarks under both the Private and Public columns.

Now run the game to see if the game performance has improved and micro stuttering is fixed.

Chat Settings Adjustment

In crowded areas like towns, adjusting chat settings can potentially improve FPS. Turn off loot, currency, and experience gain notifications in the chat settings within Lost Ark to reduce the processing load during gameplay.

DirectX Version Check

Verify that Lost Ark is set to use DirectX 11. Some players experienced issues when the game switched unexpectedly to the DirectX older version after an update. Check and adjust this setting within the game options.

Consider Memory Upgrade

Upgrading your RAM may lead to a significant increase in FPS. Users noted improvements after upgrading from 16GB to 32 GB. If feasible, consider upgrading your system’s memory.

Check CPU-GPU Compatibility

Ensure compatibility between your motherboard, CPU, and GPU. Compatibility issues might contribute to performance problems. Check the specifications of your components and make necessary adjustments or upgrades.

Set High-Performance Mode

If your computer’s power profile isn’t set to High performance, it could be throttling performance.

To access Power Options in Windows:

  1. Press Windows + R, type “powercfg.cpl” into the Run window, and then press Enter.
  2. Select the radio button next to the High-performance power plan. You may need to click Show additional plans first.

Solo Gameplay Optimization

For optimal performance, run Lost Ark solo without additional applications or streams running in the background. Close unnecessary programs to free up system resources for the game.

Check PC Overheating

Overheating can cause performance issues with any computer, and the symptoms can vary depending on the situation.

Some common signs of overheating:

  • Weird fan sounds.
  • Blue screen of death.
  • Constantly reboots or shuts down.
  • Non-fan-based CPU overheating.
  • High temperature.
  • Your computer sounds like it might take flight at any moment.

Optimize NVIDIA Control Center

Adjusting settings in the NVIDIA Control Center can enhance GPU performance for Lost Ark. Follow these steps:

  1. Open the NVIDIA Control Center on your system.
  2. Navigate to the “Manage 3D settings” section.
  3. Set the “Power management mode” to “Prefer maximum performance.”
  4. Enable “Ultra Low Latency” for reduced input lag.
  5. Turn on V-Sync and G-Sync for smoother gameplay.

Use MSI Afterburner

MSI Afterburner allows manual GPU adjustments for stable performance. Exercise caution while overclocking. Follow these steps:

  1. Download and install MSI Afterburner.
  2. Open the application and adjust the GPU fan speed manually if necessary.
  3. Consider overclocking cautiously to boost GPU performance.
  4. Ensure your system can handle the increased load to prevent instability.

Optimize Internet Connection

Online stuttering issues may be resolved by optimizing your internet connection. Switch to a wired connection for stability. Follow these steps:

  1. Connect your computer to the router using an Ethernet cable.
  2. Disable Wi-Fi to ensure a wired connection.
  3. Test the game’s performance with the improved connection.


Frame rate stability can be achieved by capping FPS. Use in-game settings or third-party tools. Follow these steps:

  1. Access in-game settings or use a third-party tool.
  2. Set an FPS cap to match your system’s capabilities.
  3. Test the game to ensure stable performance.

Close background applications

Most PC games will not perform better if multiple applications are running in the background. You need to close these apps using the Windows Task Manager.

It’s because these unwanted apps consume precious memory and CPU/GPU causing a deficiency of resources for games.

Set CPU process priority
