Hi delman, 'complex' means a model that consists of a lot of 3D Points and/or uses a lot of (high-resolution) textures.
Excessive 3D Point counts as well as the number and size of textures in use have the capacity to push a graphics card to its limits.
The faster your graphics card is and the more on-board memory it has, the lazier you can be in terms of optimisation of your scene, and the fewer times you'll reach the limits of your hardware.
What some people don't realise is that saving a few hundred dollars on your hardware may in fact result in higher labour costs further down the line as you have to spend time on re-exporting models (with less details) as well as hiding some models in Lumion on a per-clip basis, just to avoid exceeding the capabilities of your hardware.
I'm not saying you should always pick the most expensive PC out there, but if you have a decent budget, try to aim for components that are on the top 20%+ list of the PassMark site.
