Autocad problem 2016 slow

[naughtyswi]

Hi.
until a few days ago I used autocad 2014 without any problem. I installed the 2016 version and I can't work in 3d anymore, the pointer goes to snaps and locks me all as soon as they select some type extruded or prizes and drag. it also happens with very light files, practically empty.
I have this configuration:
intel core i5 6600
gpu nvidia geforce gtx 960
16 gb ram
I think with this configuration I should be able to work quietly with not too heavy files. deactivating hardware acceleration things improve little and not always. I updated the video card drivers but nothing changed.
What can I do?
Thank you.

....check that the management of video cards is set by bios on gtx 960

in the autocad graphic performance menu tells me he's using gtx. Do I have to check the same in the bios?
However now the problem arises only when I use the command "press and drag", the rest is back to being rather fluid.

in some cpus with integrated vga the switch should be made from bios....in my notebook I had to do so

I looked in the bios, it was set to "car", I put on "pcie", that is on the gtx, but nothing changed. so I think that even before it automatically recognized me the dedicated card.
It will be some autocad setting at this point, even because for now it seems to me to problem only on that command.
Thanks anyway.
