In fact i have tested the version on their download page ,
so i premuse it was 3.2 !

I like their advertising title
"The most powerfull 3D Toolkit on the world ?"
It's a question in fact caus they say after that : We'll let you decide that !

It's pure teasing , caus when you test i think lot of people knowing others 3D engines have been really disappointed it's so so slow !
