Firstly this guide was written on the steam forums however its gone missing so I am going to try to make my own version for the benefit of people who have some problems with the Wakfu client.

I do not know much about java however this worked for me so I am hoping it will work for others.

Wakfu uses java and java eats more memory as times go along, if you play more than 1 account, this problem because worse. So you would need to frequently quit the game and relaunch in order for a temporary fix.

This guide is for a Windows PC as I am not familiar with Mac OS or Linux and how their java works.

To get an enlarged image, click on the image once.

Go to the wakfu launcher, go to options, untick "use the java version provided by Ankama".


You may need to download java.

Go to Control panel.



Go to java (whatever version you have)



Go to Java tab, View, you may need to click add. Double click on "run time parameters" then type in the code (see below) I use -Xms4096m & -Xms4096m .



Now lets talk about how much memory we should allow java to use. I personally let Wakfu use about 700-800 Mb per account I have 8Gb of RAM. I can easily play 6 accounts on -Xms4096m & -Xms4096m.

Xms sets the initial amount of memory.

Xmx sets the static amount of memory.

So depending on the amount of RAM you have and the amount of RAM you can allocate for Wakfu that is up to you. Please remember give your operating system enough RAM to operate.

The code for this is:-

• -Xms512m & -Xmx512m - not recommend I think you need more than this
  
• -Xms1024m & -Xms1024m
  
• -Xms2048m & -Xms2048m
  
• -Xms3072m & -Xms3072m
  
• -Xms4096m & -Xms4096m

To seperate the Xms and Xmx just make sure to use 1 space.
