How can you improve performance within Lumion 12?

Reduce the resolution of your monitor or make the Lumion window smaller (the fewer pixels it needs to render, the higher the framerate is). Alternately, change the Editor Resolution setting on the Settings screen to something other than 100%. On the Settings screen, lower the Editor Quality’s star rating.

If a Lumion Project is too sophisticated for your hardware and doesn’t have enough system memory and virtual memory to run properly, performance will suffer.

Experience and knowledge of the requirements for the Lumion programme are essential for effectively designing a Scene and keeping a Project within the ranges to which your hardware can operate.

The following are signs that a project is too sophisticated for your hardware:

• Even with a strong graphics card, the FPS is uncomfortably low (1–10).
• While navigating the Project, the camera stutters.
• lack of response when clicking.
• Long or erratic render times
• The window says “Not responding,” and the screen occasionally turns white.

We advise making sure your PC satisfies the system requirements for Lumion if your Project exhibits one or more of these symptoms. Additionally, it’s critical that the graphics card matches the complexity of the project you’re working on.

The Project can then be optimised, and you can change your parameters to enhance performance.

1. Make sure your computer satisfies the system requirements:

To determine whether your hardware is compatible with Lumion and your Projects, follow these instructions.

1.1: Does your computer meet Lumion’s system requirements?

Check the following link to see if your computer satisfies or surpasses Lumion’s minimal system requirements:

• Website for Lumion Lumion 12 system requirements
• Knowledge Base: What type of PC is required for Lumion 12?
• Which graphics hardware is required for Lumion 12? Knowledge Base

You’ll need to upgrade your PC’s hardware if it turns out that it doesn’t satisfy the minimal specifications in order for Lumion to function properly.

Continue to the step below if the PC satisfies the prerequisites.

1.2: Is your computer—and in particular, the graphics card—appropriate for your projects?

Check to see if the graphics card matches the complexity of your project as described in these articles:

• Which graphics hardware is required for Lumion 12? Knowledge Base

Define a level of hardware using the chart in section 2.2:

• How Do You Calculate the “Complexity” of Your Projects?

1.3: Upgrade the software on your computer

Make sure your graphics card driver and Windows version are current if you’ve determined that your PC is compatible for Lumion and your projects.

• Knowledge Base: How do you set up the most recent operating system needed to operate Lumion?

Additionally, make sure your computer has sufficient virtual memory to handle your project. We advise at least 50 GB and, for really complex Projects, 100–150 GB.

• Knowledge Base: How do I modify Windows’ virtual memory settings?

1.4: Frequently check the Performance Monitor to see how difficult your project is.

To avoid overtaxing your hardware and building Projects that are too sophisticated for your system, it is a good idea to keep a watch on the Performance Monitor.

The FPS and Memory lights move from white to orange to red for warning as the Project becomes more complicated.

When you should stop adding items or check the content, the orange signal tells you when to do so.

The Project has already reached a point of slow performance when the FPS approaches red and displays directly on the monitor, therefore you must immediately study the alternatives below.

2. Optimize your Project:

Lumion does not prevent you from continuously adding additional content to your Project, but your hardware can only handle so much data before it starts to degrade performance. You will eventually realise that the content has an effect on screen redraws and render times if you keep raising the Project’s load.

You should consider the following factors when creating your Project in order to improve Lumions’ performance in the Editor.

The quantity and degree of difficulty of the imported models in your project.

Performance is impacted by the 3D Point Count of imported models.

In the Performance Monitor (top right of the screen in Build Mode), the total number of 3D points is shown in red, indicating the complexity and weight of your project:

The intricacy of the imported models will have a greater impact on the 3D point count. Additionally, the project may become slower the more 3D points it has.

Reduce the resolution of your monitor or make the Lumion window smaller (the fewer pixels it needs to render, the higher the framerate is). Alternately, change the Editor Resolution setting on the Settings screen to something other than 100%. On the Settings screen, lower the Editor Quality’s star rating.

If very complicated or too many imported models are not optimised before being imported, they may have a high 3D Point Count and a significant influence on performance, such as some trees or extremely detailed furniture. When you import a model that is excessively sophisticated and likely to have an effect on performance, Lumion will alert you.
