This article details how to fix the following issues

  • An 'Unknown Graphics Card' error
  • A 'Missing .dll' error
  • Patches, green squares, flashing lines, flickering, or blacked out areas in the 3D view
  • Graphics are slow and unresponsive

OptiSurface Designer can use a graphics card or an integrated graphics processor (IGP) with 3D capabilities to run the display graphics faster. Most computer newer than 3yrs old include these capabilities. For many rendering issues, you may need to update your graphics card driver.

Here's what you need to do, depending on your computer:

  • Laptop computers: Visit the laptop manufacturer's website (Dell, Toshiba, Sony, etc.) to get the most recent driver for your graphics card or IGP.
  • Desktop computers: Visit the graphics card or motherboard (for IGPs) manufacturer's website to download the latest driver for your system.

Note: We strongly advise against installing graphics card or motherboard chipset drivers in beta release.

Determine what graphics card you have.  If you don't know what kind of graphics card is installed in your computer, you can use a program to determine your computer's hardware, operating system, and graphics card:

  1. Go to Start > Run.
  2. Type dxdiag in the box.
  3. Click OK.
  4. Click Yes to the prompt, and the program will begin running.
  5. Click the Display tab, and you'll find the name of your graphics card listed under the 'Device' section.

If your drivers are more than six months old, we recommend downloading an updated driver from your graphics card or computer manufacturer's site.
