Open notepad and begin to construct a string with the following properties and adjust the bold text to suit your needs.

-refresh 144

This will force the refresh rate and the above would only apply if you play on a 144hz monitor. Adjust the number to accommodate your setup.


This controls the maximum amount of RAM to allocate to the game. If you have 16GB of RAM and wish to allocate 13GB, then the input you’d place after the equal sign would be 13000.


This will let your operating system decide the amount of memory to use while the game is running. Since the game is not optimized yet, allowing your system to control this will improve gameplay significantly.


This does exactly as it specifies. This will ensure that all of your CPU cores are being used while running PlayerUnknown’s Battlegrounds.


If you’re still having a difficult time running the game then add this to your current Steam launch options. This will change shading from DirectX 11 to DirectX 10. It won’t look as stunning, but it should run a bit more smoothly.

Applying Steam Launch Options

Your final product should look something like this but with your own inputs.

-refresh 144-maxMem=13000-malloc=system-USEALLAVAILABLECORES-sm4

Copy the entire text and apply your Steam PUBG launch options by doing the following:

  • Open Steam.
  • Navigate to your Steam Library.
  • Right-click on Playerunknown Battlegrounds.
  • Click on Priorities.
  • Paste your launch settings.
  • Press OK.

Try launching the game after you’ve done this. Hopefully, this has improved your gameplay experience. If you’re still having trouble, you can adjust some of the inputs above. You can also read more on how to do this in the Steam Support article about how Launch Options work which is sure to help you achieve your goal.
