Storyline 360 x64 no difference with x32

Hello, 

I tried the new SL 360 64bits for few days and there is absolutely no difference with the 32 bits version. The performance is still poor. Actually the software is slow and not reactive, even if the slide is not that full of elements, some check boxes with 3 lines of text is enough to slow SL. There is huge latency between the the time of an action (mouse click, grab, etc.) and the time when we see it at the screen. I'm used to it since months but was expecting that the x64 version will resolve this issue.

My PC:
CPU : i7 6820HQ 2.7 Ghz
RAM : 64 Gb DDR4
GPU: Quadro P2200
SSD : Nvme 1 To

My computer runs other demanding programs like a charm. Storyline is not that demanding and it's really slow.
