Hi Peter, the easiest way to answer that question is to contact your local reseller in order to get a 7-day trial version of Lumion 5.0.
You'll then know exactly how responsive it is to work with, and how large models you can import.
I would also recommend that you look up the PassMark
score for the GTX 680M. There's more information here
As far as I know, nobody at Act-3D or on the forum has tested Lumion on Windows 10, so your guess is as good as mine
I'd certainly be interested to hear what the result is if you're going to give it a try.
