The following guidelines describe which graphics card and minimum PassMark points you will need based on the complexity of the Scenes you expect to work on:

Ultra complex Scenes: (for example a highly detailed city, airport or stadium, highly detailed interiors, multi-floor with interiors)

  • Minimum 10,000 PassMark points
  • 8 GB+ graphics card memory.
  • DirectX 11 compatible.
  • The CPU should have as high a GHz value as possible, ideally 4.2+ GHz.
  • Examples: NVIDIA GTX 2080 Ti (11 GB memory), NVIDIA GTX 1080 Ti (11 GB memory)

Very complex Scenes: (for example a large park or part of a city, detailed to highly detailed interiors, multi-floor with interiors)

  • Minimum 8,000 PassMark points
  • 6 GB graphics card memory.
  • DirectX 11 compatible.
  • The CPU should have as high a GHz value as possible, ideally 4.0+ GHz.
  • Examples: NVIDIA GTX 1060 (6 GB memory), Quadro K6000.

Moderately complex Scenes: (for example a moderately detailed office complex)

  • Minimum 6,000 PassMark points
  • 4 GB graphics card memory.
  • Rendering movies in 4K resolution (3840×2160 pixels) requires a minimum of 6GB graphics card memory.
  • DirectX 11 compatible.

Simple Scenes: (for example a small building/interior with limited details)

  • Minimum 2,000 PassMark points
  • 2 GB graphics card memory.
  • Rendering movies in 4K resolution (3840×2160 pixels) requires a minimum of 6GB graphics card memory.
  • DirectX 11 compatible.

2. What’s the difference between NVIDIA Quadro and NVIDIA GTX/RTX graphics cards?

  • Non-Quadro GTX/RTX graphics cards can render “game” graphics very fast (Lumion is built with a game engine).
  • Quadro cards can render lines very fast in CAD software.
  • Non-Quadro GTX/RTX graphics cards have got 8 digits of precision for position, rotation and scale values.
  • Quadro cards have got 16 digits of precision for position, rotation and scale values.

Many of our customers use GTX/RTX graphics cards when working in both Lumion and in their CAD software. Although there are slight differences between Quadro and GTX/RTX graphics cards, GTX/RTX graphics cards work fine in CAD software. If you need to choose between an expensive Quadro graphics card and a cheaper GTX/RTX graphics card with the same number of PassMarkpoints, the GTX/RTX graphics card is usually a good choice.

3. Multiple graphics cards (SLI/Crossfire), NVLink and graphics cards with more than 1 GPU

Multiple graphics cards (in NVIDIA SLI, AMD Crossfire or NVLink configuration) will not boost the performance in Lumion. Lumion will simply use the graphics card that is connected to the monitor that the Lumion window is running on.

Some of our users make use of 2 graphics cards connected to 2 different monitors. That way, you can use Lumion on 1 monitor/graphics card while the other monitor/graphics card is used for other applications. This sort of set-up tends to have a negligible impact on performance.

4. Graphics cards for Dell & HP workstatations

IMPORTANT NOTE FOR DELL & HP OWNERS: Some power supplies in Dell and HP computers are known to cause instant reboots when you start rendering images/movies in Lumion. A number of our users reported that the reboots stopped occurring after they replaced the Dell/HP power supplies with power supplies from reputable manufacturers (80+ gold-rated).

The power supplies of certain Dell workstations will only work with the graphics card that they are delivered with (or low to medium-end graphics cards). Unless you can replace the Dell power supply with a more suitable one, you will often not be able to use high-end graphics cards like the GTX 1070, 1070 Ti, 1080, 1080 Ti and Titan Xp. There is a workaround which involves limiting the amount of power to the graphics card via an app called MSI Afterburner, so that the graphics card runs slower. Please enquire at the Lumion Support Center if you need assistance with this process.
