No, we don't, sorry. I'm not sure if there are any members here who have even bought one as yet.
Any graphics card needs to support the model data, the textures and surface mapping of the model, and the other graphics results on a model such as Scene effects. AutoCAD stores its models in a format that when the required conversion to Lumion takes places to a polygon mesh, will increase the required data space on the card. So it is not really possible to use the file size in AutoCAD as an indication of how much space is going to be required on the card.
Furthermore, when the graphics card memory is fully used, the system will then access System Memory (fast), and then hard drive memory (drives and SSD) (slow) to store the data. So everything does not need to fit on to the card. That's why I mention the Titan extra memory will simply be the fastest handling memory.
In other words, you will get by with either an RTX 2080 Ti or RTX Titan. The Titan will handle things a little better if the total Scene data requirements exceed the 11GB.
