autocad works slowly with retini

[angeloCAD3D]

Good evening, guys.
I recently bought a new p50 lenovo (excellent workstation with intel xeon processor and nvidia picture graphics card m2000m). I started using autocad today and when I use the retini I noticed that the program slows down so much to go to snaps or crash. I add that I use a version for students; above all I have already set the video card as default when opening the program and I updated it with the latest drivers but continues to give problems! advice?
Thank you very much:wink:

I didn't know the command, it goes much smoother, thank you so much! but solved the problem I keep not explaining why it is so slow despite the graphics performance that the pc should ensure! Thank you very much

installed autocad service packs?

Excuse me if I answer only now; I have installed the service packs but unfortunately, using the student version, I have not available all the news from these (including 4k monitor support). precisely for this reason I began to think that the slowness of response is also given by the fact that the machine has to focus on the lack of compatibility between program and display, rather than performance as well. Of course, not being an expert, correct me I was wrong intuition.
Sorry again for the delay and thank you for any contributions
