Fix 1: Make sure your PC meets the system requirements for DayZ

If your PC fails to meet the system requirements for DayZ, the game lag issue may occur. So, before trying other fixes, you should check if your PC meets the system requirements for the DayZ.

Below are the minimum and recommended system requirements for DayZ:


OS:Windows 7/8 64-bit
Processor:Intel Core i5-4430
Memory:8 GB RAM
Graphics:NVIDIA GeForce GTX 760 or AMD R9 270X
DirectX:Version 11
Storage:16 GB available space
Sound Card:DirectX®-compatible
Additional Notes:Internet connection
If your PC fails to meet DayZ minimum system requirements, you may not be able to run the game properly on your PC. In such a case, you need to upgrade your hardware first. If you don’t know how to check the DirectX version on your PC, you can refer to the first step in the post: Download DirectX 12 for Windows 10 [SOLVED]


OS:Windows 10 64-bit

Fix 2: Try other servers

A dedicated server is important for playing DayZ without lags. If your PC meets the recommended system requirements for the game but DayZ still lags, you can try play the game in another server.

It’s recommended that you find a public server and play on it, because the public servers are guarenteed to be dedicated servers.

If DayZ still lags, don’t worry. Try the next fix, below.

Fix 3: Update your drivers

If your graphics drivers or network driver is corrupted or outdated, the game lag issue will occur. If DayZ still lags after you tried Fix 2, it’s time to update your drivers.

Updating the graphics driver can not only enhance the performance of your graphics card, but also avoid many unexpected computer issues in the future. By updating the network driver, your can enhance the network stability on your PC and reduce network latency.

There are two ways to update your drivers: manually and automatically.

Update your drivers manually – You can update your drivers manually by going to the manufacturer’s website, and searching for the latest driver for your device.

Be sure to choose the driver that’s compatible with your exact device model and your version of Windows.


Update your drivers automatically – If you don’t have the time, patience or computer skills to update your graphics driver manually, you can, instead, do it automatically with Driver Easy.

Fix 4: Modify the graphics settings

Modifying the graphics settings is another easy fix to reduce lags in DayZ. You need to modify the graphics settings both in Nvidia Control Panel and in the game.

Modify the graphics settings in Nvidia Control Panel

  1. On your keyboard, press the Windows logo key and R at the same time to open the Run dialog. Then type control and press Enter to open Control Panel.
  2. View Control Panel by Large icons.
  3. Click NVIDIA Control Panel to open it.
  4. Click 3D Settings and select Adjust image settings with preview. Then select Use my preference emphasizing and drag the slider to the left.

Lower the in-game graphics settings

  1. Launch DayZ and modify the following in-game video settings:

    Vsync = Disabled
    Terrain = Very Low
    Shadows = Disabled
    Clouds = Disabled
    Video memory = Auto
    Texture detail = Low
    Texture filtering = Low
    Antialiasing = Disabled
    Alpha to coverage = Disabled
    Edgesmoothing = FXAA Low
    Postprocess quality = Disabled
  2. Apply the changes and launch DayZ.

Performance tweaks in Steam

1. Open Steam and go to LIBRARY. Right-click on DayZ and select Properties. Then click on Set commandline options.

Explanation for the command line we’re going to type:

  • -nosplash – removes the Bohemia Interactive splash page.
  • -noPause – gets you into the game faster.
  • -cpuCount=4 – you should set the value to the number of cores your CPU has.
  • -maxMem=8192– you should set the value to the total amount of RAM your system has. For example, 1024 is for 1GB and 4096 for 4GB.
  • -exThreads=8
  • -malloc=system – allow modern CPUs to allocate more resource
WARNING: Legacy launch parameters are deprecated since 0.54 Build. Use it with caution, especially the one related to memory.

To check the number of cores:

  1. On your keyboard, press the Windows logo key and X at the same time, then select Task Manager.
  2. In Task Manager, navigate to the Performance tab and select CPU on the left panel. On the right, you can see the number of cores your CPU has.

This command line looks like this:

-nosplash -noPause -cpuCount=4 -maxMem=8192 -exThreads=8 -malloc=system

Fix 5: Install the latest DayZ patch

The developers of DayZ release regular game patches to fix bugs. It’s possible that a recent patch has caused this issue, and that a new patch is required to fix it.

If a patch is available, just download and install it to see if it can fix the game lag issue; if there’s no patches available, or if the issue persists after you installed the latest patch, try the next fix, below.

Fix 6: Run a defrag on your hard drive

It’s a good choice to run a defrag on your hard drive if DayZ is not installed on a solid state drive (SSD), or if you just installed a DayZ patch. Here’s how to do it:

  1. On your keyboard, press the Windows logo key and type defragment. Then in the list of search result, click Defragment and Optimize Drivers.
  2. Select the drive where DayZ is install and click Optimize.
  3. Click Close after the optimization process completed.

Launch DayZ to see if this fix works. It’s time to contact the game developers for further assistance.
