Anonymous — Tue, 30 Jan 2018 15:04:41 GMT

I dont know what's happend. Every drawing is full of jumping lines, when i scroll/move or what ever all the lines start flickering around.

Anyone has here knows what this is, or why it has started, and formost, how to end it?

Best regards Thomas Ljunggren

Turn off LINESMOOTHING and LINEFADING to see if that helps before you turn off hardware acceleration.

Turning of linesmoothening did the job:)

I did however notice that Autocad uses my inactive internal videocard "Intel HD Graphics 530" instead of my "NVIDIA Quadro M300M".

Is it possible to change videocard in Autocad somehow? There are no editing options under hardware in "3dconfig"

I use Autocad 2018

Most desktop/workstation motherboards give you the option to disable the onboard graphics in the BIOS/UEFI. To access that menu, reboot your computer and watch for the options that are very briefly displayed on the screen. It's usually a function key like F2 or the Delete key that takes you there.

This option is far less prevalent on laptops, which appears to be what you have, but you can give it a try.

From the BIOS/UEFI, you'll have to find the appropriate option to turn off or disable the onboard Intel graphics, as the screens you'll see vary from manufacturer to manufacturer. After that, AutoCAD will have no choice but to use the dedicated card.

Professional graphics cards usually come with software that allow you to disable the onboard graphics as well. I've not had success with that, but it may be your only option on a laptop.
