While working on Ideate Tech support, a client had an issue with lines showing up blurry in AutoCAD 2015. This turns out to be a known issue that Autodesk is looking into. There are some work-arounds, however.  

The solution

It is most likely related to your graphics card driver.  Below is a list of possible fixes:

Option 1

  1. Turn Smooth line display off in the Graphics Performance Box

Option 2

  1. Edit special settings of the NVidia driver, “NVidia FXAA Anti-Aliasing” = OFF. You can find the NVidia control panel by right clicking anywhere on your desk top and choosing the NVidia Control panel.  Once in there, go to the Manage 3D settings, and choose AutoCAD on the Program Settings tab.  From there, you can make sure Antialiasing – FXAA is turned off.  Refer to the image below.
  2. Turn Hardware Acceleration on in AutoCAD

Option 3

  1. Uninstall AutoCAD 2015
  2. Update your Graphics card Driver
  3. Re-install AutoCAD 2015

Check out the documented solution from Autodesk, Lines Display Blurry or Unsharp in AutoCAD 2015 and Newer.
