Fix 2 – Verify integrity of game files

Missing or corrupted game files will prevent the game from working smoothly. To see if that’s the case with Lost Ark, you can verify the integrity of the game files.

  1. Launch the Steam client and select the Library tab.
  2. From the game list, right-click Lost Ark and select Properties.
  3. Click the Local Files tab, and click Verify integrity of game files.

It may take a couple of minutes for the process to complete. Once done, restart the game to test the issue. If the problem persists, move on to more fixes below.

Fix 3 – Update your graphics driver

Many game issues tend to be driver-related. That said, if you’re using a broken or outdated graphics driver, Lost Ark may not launch the right way. For the best in-game performance, you should update your graphics drivers on a regular basis.

Main graphics card manufacturers usually roll out new drivers for the latest titles. You could visit their official websites (AMD or NVIDIA), find the driver corresponding with your operating system, download and install it manually.

If you don’t have the time, patience or computer skills to update your graphics drivers manually, you can, instead, do it automatically with Driver Easy. Driver Easy will automatically recognize your system and find the correct drivers for your exact GPU, and your Windows version, and it will download and install them correctly:

  1. Download and install Driver Easy.
  2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
  3. Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

    You can also get the drivers you need for free, but you’ll need to download them one at a time and manually install it.
The Pro version of Driver Easy comes with full technical support.
If you need assistance, please contact Driver Easy’s support team at support@drivereasy.com.

A driver update will greatly improve your game experience. If this doesn’t resolve the problem, check out the next solution.

Fix 4 – Run Lost Ark as an administrator

Running the game as an administrator is a simple workaround to resolve issues due to the lack of administrative rights. Simply give it a try and see if this trick works for you.

  1. Go to the Lost Ark installation folder, which you can find at C:\Program Files (x86)\Steam\steamapps\common\Lost Ark\Binaries\Win64. If it’s not there, launch your Steam client, right-click the game, select Properties > Local Files > Browse local files.
  2. Right-click the LOSTARK.exe file and click Properties.
  3. Select the Compatibility tab. Tick Disable full-screen optimizations and Run this program as an administrator.
  4. Click OK.

Try launching the game to see how things go. Still no luck? Take a look at the next method.

Fix 5 – Turn off unnecessary programs

When you have too many programs running in the background, it can eat up the system resources (CPU and bandwidth), and therefore make your Lost Ark not launch or work. To solve this, just shut down all the unnecessary programs besides Steam and the game launcher.

  1. On your keyboard, press the Windows logo key and R at the same time to invoke the Run command. Type taskmgr and press Enter.
  2. Select the program and click End task until you close all the unneeded applications.

Restart and check the game. If it still can’t get past the loading screen, continue to Fix 6.

Fix 6 – Switch to DX9

Quite lot of Lost Ark players experienced performance issues such as crashing or stuttering when running the game on DX11. If you’re one of them, launching the game in DX9 may mitigate this problem.

  1. Launch Steam and go to the Library tab.
  2. Right-click Lost Ark from the game list and select Properties.
  3. Under Launch Options, type -force-d3d9 and close the window.

Relaunch Steam and Lost Ark. So is it able to work correctly in the DX9 version? If not, try the next fix below.
