Bisq is known to be a resource-hungry application, so some users may want to '''reduce memory usage'''.

== Persistent setting and Windows work-around ==

If you'd rather not specify the RAM parameter every time you start Bisq, you can specify it in <code>Bisq.cfg</code> so it automatically takes effect every time.

First, make sure Bisq is closed.

Your <code>Bisq.cfg</code> file is in the directory with your Bisq binary (this is different from your [[Data_directory|data directory location]]). See [[Running from the command line|locations for each OS here]].

Navigate to the directory with your Bisq binary. Using Windows as an example, this would be <code>$home\AppData\Roaming\Bisq\</code>.

<code>Bisq.cfg</code> should be in the <code>app</code> directory.

Open that file in a text editor. Look for the <code>[JavaOptions]</code> section, and a line in that section that look something like <code>java-options=-XX:MaxRAM=8g</code>. Change it to <code>java-options=-XX:MaxRAM=4g</code>, or add it if it's not already there.

 [JavaOptions]
 java-options=-XX:MaxRAM=4g

You can also try disabling the hardware graphics acceleration by adding the following line at the end of the <code>Bisq.cfg</code>

 [JVMOptions]
 -Dprism.order=sw

Save the file, close it, and then open Bisq.<!-- BISQ VERSION: general -->
