To be frank I expect much better performance than this, even with the editor settings maxed out.
Hey Will, apologies for the late reply.
There are 3 factors at play here:1)
Your monitor resolution is set to 2560x1440 and the number of pixels has a significant impact on performance. For example, on a 3840x2160 monitor, the graphics card has to render four times as many pixels as on a 1920x1080 monitor, so even a GTX 1080 Ti can sometimes struggle when running 3D games, flight simulators etc at max settings. In other words: the lower the resolution the better. You can 'simulate' a lower resolution without having to change your monitor resolution by using the 'Editor Resolution' toggle buttons on the Settings
The 'Editor Quality' setttings have an impact on performance, i.e. the number of stars on the Settings
screen. In addition, the 'High quality trees in editor' and 'High quality terrain in editor' options also have an adverse effect on performance.3)
The effects in Photo/Movie
mode can have a serious impact on the preview framerate, especially the 'Reflection' effect when you switch the 'Preview Quality' in the effect to 'Normal' or 'High' as each reflection plane that is added to a scene means that the whole scene has to be mirrored and rendered once more per frame in order to display the reflections for the given reflection plane.
Just to give you an idea of my framerates with a GTX 1070 (laptop version), running at 1920x1080 and with unmodified effects and no changes to the 'Living room interior' demo scene:1) Build
mode in 4 star quality with the 'High quality trees in editor' and 'High quality terrain in editor' options turned on = 29 frames per second.2) Movie/Photo
mode in 4 star quality with the 'High quality trees in editor' and 'High quality terrain in editor' options turned on = 29-35 frames per second.
Try comparing those numbers to yours when using the same monitor resolution and editor quality settings.
Why does lumion only want to use 2GB of memory???
Thanks to your diagnostics file, we now know the reason.
The reason is that on Windows 7
, DirectX can't retrieve the correct graphics card memory parameter for cards with more than 4GB memory. However, it's purely a cosmetic issue and you can rest assured that all of the graphics card memory is used (in addition to system memory and virtual memory).

: Why does Lumion claim that my graphics card only has 4GB memory?
Microsoft fixed this error in Windows 10 (in case you're thinking about upgrading).
