Hi,

 

welcome @Anonymous.autodesk.com!

 

Which operating system, which graphic card and which graphic card driver are you using?

 

One try (for now): turn off hardware acceleration (command _GRAPHICSCONFIG) and see if that gets better.

And when you have that dialog open (where you turn off hardware acceleration), please show us a screenshot.

In fact, the flickering happens to be more when switching off Hardware Acceleration

Hi,

 

AutoCAD does only see the Intel HD graphic card (which is not a good one for AutoCAD), but not the nVidia you listed as built in.

Disable your Intel HD (in the BIOS) so AutoCAD get's the nVidia gc.

Hi @Anonymous,

 

It does appear from your image that AutoCAD is using the incorrect graphics card.

 

Here is an article that might help in configuring your graphics card software to force the nVidia card to be used with AutoCAD.
