Help needed to change java max heap size
Hi,

Can someone help me with this please? I have seen FAQS but adding -Xmx in ini file but seems no effect on v6.5. I am on Windows10 Pro 64bit 20H2 latest.

Sorry, the post was incomplete. I have 16GB of RAM but even changing requirement to -Xmx6g doesnot have any effect. It still uses only 2GB of ram though I have more than 50% free of 16GB

Are you sure your file is named SweetHome3D.l4j.ini and not SweetHome3D.l4j.ini.txt?

Hi Emmanuel,

Just checked, changed from 6GB to 4GB and now it is using 3GB instead of 2. Is it OS dependent?
