I fixed the problem another way by downloading and installing Java3D 1.5.1 for AMD 64

http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-java-client-419417.html#java3d-1.5.1-oth-JPR

Two days ago I downloaded SH3D. The 3D view is sluggish.
I run Win10 on my computer.
SH3D'S "About" windows says
Java 1.8.0-54/64 bits
Version Java 3D 1.60
When I start with the launcher "SweetHome3D.jnlp" the 3D is running perfectly smooth.
How can I fixed that?
Regards
