Nvidia Quadro K5200 refresh issues

[GERALDRICHARDSON4370]

I am running AutoCAD 2018 (Version: O.161.0.0 AutoCAD 2018.1.2 Update) on a Windows 10 x64 box (HP Z-640). I am using an Nvidia K5200 Graphics Card, with the Autodesk certified 375.86 diver (shows as 21.21.13.7586 0f 11/10/2016 on the Graphic Card Driver properties window in Device Manager).

I am having an issue where the card fails to refresh the display after any edit command. If, for example, I delete an object, the image of the object stays on the screen until I zoom in or out. What might be causing this?

I have tried various different Nvidia drivers for my card, including the latest, but nothing changes, so I "downgraded" the one listed for AutoCAD 2018 on the Autodesk web site.

HELP!

Sounds similar to an issue I had with AutoCAD 2018.  In that case, turning on High Quality Geometry (HQGEOM=1 or enter GRAPHICSCONFIG at the command line and check the "High quality geometry" box in the popup) solved this particular issue for me.  Of course, in usual Autodesk fashion, having HQGEOM set to 1 creates other problems for me, so I typically just leave it set to 0 anyway.  In my case, I only had the problem when I had approximately 10 drawings open.

Magic!! Fixed the problem. So far so good, I will update this if any other unforeseen issues arrise, but so far so good!

Thanks very much.
