CATIA 3DEXPERIENCE lagging

Hi,

I run into issues using catia 3dexperience for students. It takes time to launch (up to 1 minute sometimes when i restore a previous session), and each time i import or open a part or assembly, the app freezes and stop responding for a moment.My experience with the app is far from smooth, yet, to my knowledge my dell precision T5810 meets all the requirement (Nvdia quadro 2000, Intel Xeon E5-1630 v4 @ 3.70GHz). I even upgraded my RAM from 16GB to 48GB and it hasn't changed.

Am I the only one to have these issues?
