Ever since Ankama Launcher arrived in your little slice of digital krosmic space, we've been adding new options to help make your gaming experience even better.

This article contains information to help you improve your client's performance for the WAKFU game.

Allocating more RAM to the game client

  • From Ankama Launcher, on the WAKFU game page when your client is closed:
    • Open the options menu (the gear icon under the "PLAY" button).
    • On the General tab, go to the advanced user settings.
 
  • If you have 32 GB of RAM:
    • On the line "Java XMS (XMS < XMX)", change the value to "4096m" or "2048m"
    • On the line "Java XMX (XMS < XMX)", change the value to "4096m"
 
  • If you have 16 GB of RAM:
    • On the line "Java XMS (XMS < XMX)", change the value to "2048m"
    • On the line "Java XMX (XMS < XMX)", change the value to "4096m"
 
  • If you have 8 GB of RAM:
    • On the line "Java XMS (XMS < XMX)", change the value to "1024m"
    • On the line "Java XMX (XMS < XMX)", change the value to "2048m"
 
  • If you have less than 8 GB of RAM:
    • On the line "Java XMS (XMS < XMX)", change the value to "512m"
    • On the line "Java XMX (XMS < XMX)", change the value to "1024m"
 
  • If you want to reset the default values:
    • On the line "Java XMS (XMS < XMX)", change the value to "512m"
    • On the line "Java XMX (XMS < XMX)", change the value to "768m"
 
  • Finally, close the options page and launch your WAKFU client.

​​​​​​Allocating more RAM to the client can often fix the following problems:
  • Persistent black loading screen when entering a new game area
  • Unstable frame rate ("freezes" or "micro-freezes")
  • Game instability

Frequently Asked Questions

 

What is "RAM"?

RAM, which stands for Random Access Memory, is your machine's "short term memory". It's used to store all the information being processed by the software you're using. In other words, RAM is partially responsible for how quickly the different software and tools on your machine will run.
 

What is Java XMS and Java XMX?

The settings Java XMS and Java XMX specify, respectively, the minimum and maximum amount of memory allocated for an application. This means that your Java application will launch with a minimum XMS level of memory and a maximum XMX level.

 

How can I find out how much RAM is installed and available on my Windows PC?

  • Open your Windows Settings (from the Start menu or by using the keyboard shortcut Windows+I).
  • Open the System menu.
  • Next, open the "About" sub-menu.
  • The value displayed on the "Installed RAM" line represents the amount of RAM installed on your Windows machine, and the "Usable RAM" value is the amount that's actually available.
 

How can I find out how much RAM is installed and available on my Mac running macOS?

  • Open the Apple menu at the top left of the screen.
  • Click on the "About This Mac" sub-menu.
  • The value displayed on the "Memory" line represents the amount of RAM installed on this Mac.
    • To see how much memory is being used, and thus how much is available, you'll need to open the Activity Monitor and check the Memory column.
 

My client shows a black screen and stops loading. What should I do?

You may have allocated more RAM than is available on your machine, and we recommend that you reset the default values.


Enjoy your optimized WAKFU experience!
