Gabriele, I think you have misunderstood something. Channels in Quest3D (which are also used in Lumion) are not scripts. They're actually compiled native C++ code from Visual Studio and are executed very very fast, so it makes no sense to claim that Lumion (and by extension, Quest3D) need to be "reprogrammed from scratch with C++ code"
As I already mentioned in my reply to one of your earliest posts, the Quadro CX card you're using is far from ideal for use with Lumion. If you check out some 3D benchmarks you'll notice that they are comparable to ATI 38xx cards, so you've done the right thing by ordering the 580 Phantom card!
Regarding the responsiveness of the interface, it is indeed affected by low frame rates but as Ferry mentioned the UI responsiveness has in fact been improved recently, although one of the button types (Modify Object -> Menu) had somehow escaped from this treatment. It has been fixed in the next update though. And as Arthur already said, you can adjust the Star modes and the resolution slider in the Home section to improve your frame rate.
