General display and crash issues after applying Update 1 in AutoCAD Civil 3D 2011

These issues are generally related to an unsupported graphics card driver, or an unsupported graphics card. 
Even if you were not experiencing issues prior to installing Update 1, it is recommended that you confirm that you are using a supported graphics card and driver.  Use the link below to look for your graphics card in the Graphics Hardware List and ensure that you are up to date with the lastest driver.
Certified Hardware
If it appears that you are running a supported graphics card and driver, or after updating your driver you still experience one of more of these issue, you may need to perform the following workaround for a resolution.
  1. Inside of your application, type 3DCONFIG at the command line.
  2. In the dialog box that appears, select the Manual Tune button.
  3. At the top of the Manual Performance Tuning dialog box, toggle the 'Enable hardware acceleration' option.
  4. Select OK and OK to return to the drawing workspace.
  5. Repeat steps 1-4 again to toggle the 'Enable hardware acceleration' option back to its original setting.
Note that it not necessary to disable the hardware acceleration.  However, toggling this setting should resolve the issues.
