Hello again, Vincent.
Your Quadro K2200 has got 4GB onboard memory which Lumion will fill up first.
Once the graphics card memory is full, it will use any available system memory, i.e. 32GB minus however much Windows and other open applications are using. This type of memory is a bit slower than graphics card memory, so you'll notice minor delays when turning the camera quickly from side to side as models and textures have to be transferred back and forth between the graphics card memory and the system memory.
Once the system memory is full, it will use virtual memory (The page file on the harddrive). If this occurs, you'll notice that the PC gets quite sluggish/unresponsive. If the PC also runs out of virtual memory, Lumion will eventually crash.
On your PC, Windows and the graphics card driver were out of date which meant that Lumion couldn't use the 3 different memory types. This typically causes performance issues, crashes, glitches and other unexpected behaviour (there's more information in
this Knowledge Base article).
However, now that you've updated everything you should be good to go!
