Many thanks to Emmanuel! The [font=courier new]/j3d.version=1.5.2[/font] option works for me. Not dirty trick anymore, just adding the [font=courier new]Sweethome3D.l4j.ini[/font] with changed options and everything works fine. In my case no performance issues with Intel(R) Graphics Media Accelerator, Driver 9.14.3.1177 and Windows 10 32bit, 1607.

Many thanks again!
