This works and is 100:1 better. With the java path and the SweetHome3D-3.1.jar the -Xmx4096m parameter is taken. Before I always tried to modify the sweetHome3D.l4j.ini with the -Xmx2048m... Like explained in FAQ...."Under Windows, create a text file named SweetHome3D.l4j.ini in the same folder as SweetHome3D.exe, write the max memory Java option in that file, for example -Xmx2048m for 2 GB, then relaunch Sweet Home 3D."
This doasn't work... over 1,5GB an error message is displayed.
Now I can compare the project-parts and it works...
Performance is still ok on my "slow" buissness-computer and I'm nosy about the performance on my home-PC.
