You can check the performance of your graphics card here:
Recommended minimum score for simple scenes:
- 2.000 PassMark points and 2GB of dedicated memory
Recommended minimum score for complex scenes
- 4.000 PassMark points or higher and 4GB of dedicated memory
Very complex scenes in Lumion
- Minimum 6,000 PassMark points and 6GB dedicated memory

The picture below compares popular graphics cards with respect to Lumion performance:
Multiple graphics cards (SLI) and cards with more than 1 GPU
Multiple graphics cards (in SLI configuration) or a graphics card with more than 1 GPU such as the Nvidia GTX 790 will not give you a performance boost in Lumion. In addition, Lumion will only be able to use half of the on-board memory (RAM) of cards with multiple GPUs.
For those reasons, we recommend buying the fastest graphics card with a single GPU and as much on-board memory as you can afford. The Nvidia GTX 980 is currently the best choice if your models have a lot of 3D points. However, if your models use a lot of textures, we recommend an Nvidia GTX Titan.
The framerate in Build mode can be adversely affected by your CPU, if it isn't fast enough to keep up with your graphics card. However, in practice, this is not a problem for most modern CPUs and graphics card.
The framerate in Build mode also depends on the monitor resolution. If you're only ever going to use Lumion at a resolution of 1680x1050 you will not need as powerful a graphics card as if you were to connect it to an external monitor with a resolution of 2560x1536.
