Lumion 12 requires a Windows operating system, using Windows 10 version 1809 or newer, or Windows 11 version 21H2 or newer.  

We recommend updating your Windows 10 to version 2004 or newer as it includes the Windows feature "Hardware-accelerated GPU scheduling" which improves the performance of Lumion in some Projects.

To see which version of Windows 10 or Windows 11 you currently have installed, click on the Windows button and select Settings -> System -> About, to see the version number.

The graphics card is the single most impactful thing you can do to improve your Lumion experience and performance of the render outcomes.

• Knowledge Base: Which graphics card do you need for Lumion 12?

The more graphics card memory is available the more details, textures, and models can be loaded, processed, and rendered by your graphics card. 

The CPU plays a role in telling the graphics card what to show you on your screen, and it will be working hard while you are editing your Project. The more details and objects you have in your Project, the more instructions your CPU needs to send to your graphics card.

Your RAM plays a role when a Project or model is loaded in Lumion. The more RAM you have, the bigger and more detailed these loaded Scenes and models can be.

The speed of your Hard Drive plays a big role in how fast your models and Projects are loaded. The faster, the better. NVME SSD drives are the latest technology. 

A power supply provides the whole system with the electrical current at specific wattage and voltages. It must be able to give each component enough to run well. If it doesn't, the PC may turn itself off, restart, or run at a lower performance to compensate.
