Re: 3d View suddenly impossibly slow
In Sweet Home 3D 5.5 released last week, I added the 3 following options to Windows installer to let you choose the Java 3D version and architecture used by the program when there are some problems:
/os.arch=x86 will force the installation of the 32 bit version of Sweet Home 3D under Windows 64 bit
/j3d.version=1.5.2 will force the installation of Java 3D 1.5.2 (default Java 3D version until Windows 7)
/j3d.version=1.6 will force the installation of Java 3D 1.6 (default Java 3D version from Windows 8)

To use these options, simply execute the installer in a cmd window followed by the options of your choice separated by spaces. For example:
C:\SweetHome3D-5.5-windows.exe /j3d.version=1.5.2 /os.arch=x86

For people not used to commands, this can be achieved this way:
- Press <Windows> + R keys
- Type cmd and press <enter> key
- Drag and drop the icon of the installer SweetHome3D-5.5-windows.exe in the command window
- Type a space in the cmd window
- Copy /os.arch=x86 /j3d.version=1.5.2 and paste it in the cmd window
- Press <enter> key.

From you last comments, using Java 3D 1.5.2 after updating your graphics driver might be enough to run Sweet Home 3D under Windows 64 bit, in which case you could first try to run the installer with the option /j3d.version=1.5.2

I'm looking forward to reading your comments to be able to modify the FAQ accordingly.
