SDK Performance issue

Hello Guys, I’m playing with the SDK trying to do some basic things with it and it is soooo slow up to point when it is almost not usable. I imported a simple model from Sketchfab it was converted to J3O which should be the best format for JME and when it is loaded to the scene you hardly can zoom in/out the canvas - very very slow. Also when I open the SDK it takes ~2 minutes to move from “project initializing…” to showing the project’s files and my project has no files in it yet (expect from that 1 imported model). It seems there are tons of features in the SDK but people cannot use it with such performance… Maybe it is specific for my computer? I don’t think so because in other Swing application I have it works super fast with the same model loaded. I’ll try starting from scratch with simplest model and report. Cheers! Adi
