The reason is that Windows 8 and 10 do not allow older DirectX 9 applications (such as Lumion 6.3 and older) to use more than 4 GB graphics card memory for a given application - and no system memory either.

If you're using Lumion 6.3 or older and need more than 4 GB of memory for your Projects, we recommend that you run Lumion on Windows 7 (64-bit with at least SP1).

We recommend updating your Windows 10 to version 2004 or newer as it includes the Windows feature "Hardware-accelerated GPU scheduling" which improves the performance of Lumion in some Projects.

Note that Lumion 11 or Lumion 12 requires at least Windows 10 version 1809 in order to run. Lumion 6.5 and newer requires Windows 10 or Windows 11.
