OpticStudio uses GPU-accelerated graphics for all on-screen renderings. See What Computer Should I Buy to Run Zemax OpticStudio
. We recommend that you also download and install the latest drivers for your graphics card as a matter of routine, as these are updated frequently, and that you keep Windows updated. Also, see Setting Up OpticStudio to Use an Advanced Graphics Card
for advice on configuring your graphics card.
In some cases, you might find that the graphics windows in OpticStudio display as black, as shown below. We cannot guarantee that a card without DirectX 11 or a card with old drivers will work satisfactorily. But we provide some workarounds for those situations below.
Fix # 1: Disable DirectX11
The problem may simply be that the graphics card on your system doesn’t support DirectX 11. If that’s the case, you can fix the graphics windows by disabling the DirectX 11 option.
Go to the Setup tab in OpticStudio and choose Project Preferences:
Under the Graphics option, uncheck the box next to “Use DirectX 11”: If you are using OpticStudio 16.5 or newer, there are 2 Directx 11 checkboxes. Disable them both.
Just to be on the safe side, save the Project Preferences, like this:
Close and re-launch OpticStudio, and look at any graphics window (such as 3D Layout) to see if the graphics now display correctly.
If the windows are still black, continue on to the fixes given below.
Fix # 2: Disable Modern Graphics
The latest versions of OpticStudio allow you to disable the modern graphics requirements entirely.
This is a permanent fix in cases where the computer hardware isn’t sufficient to support the new requirements. For systems that include advanced graphics cards, this solution can be used as a temporary fix while troubleshooting the graphics card.
a side effect of this setting is that the "Shaded Model" and 3D Shaded Model" buttons will be unavailable in OpticStudio, as they depend on 3D support.
Under the Setup tab, click on Project Preferences. Select “Graphics” and then find the line at the center right that says “Disable Modern Graphics.” From the drop-down, choose “All Plots.” Then save the Project Preferences. If you don’t see the “Disable Modern Graphics” option, skip ahead to Fix # 3.)
Close and re-launch OpticStudio, and open any graphics window (such as 3D Layout) to see if the graphics now display correctly.
Fix # 3: Enable Classic View
If you’re running an older version of OpticStudio, the “Disable Modern Graphics” option may not be present. In that case, you can still work around the problem by enabling plots in “Classic View.”
This is a permanent fix in cases where the computer hardware isn’t sufficient to support the new requirements, and the user doesn’t want to upgrade to the latest version of OpticStudio. For systems that include advanced graphics cards, this solution can be used as a temporary fix while troubleshooting the graphics card.
Under the Setup tab, click on Project Preferences. Select “Graphics” and find the line at the lower left that says “Enable Classic View.” Check the box. Then save the Project Preferences.
Close and re-launch OpticStudio, and open any graphics window (such as 3D Layout).
The “Graphics” tab will still display a black window:
But the “Classic” tab will now show the correct plot:
Fix # 4: Setting OpticStudio to use an advanced graphics card
Fix # 2 or # 3 should allow you to continue working in OpticStudio. But both solutions bypass any advanced graphics card in your computer system.
To find out if your computer system includes an advanced graphics card, and for instructions on how to configure Windows and OpticStudio to correctly use the card, see the Knowledge Base article: Setting OpticStudio to Use an Advanced Graphics Card
