Hello I'm sorry English Brazil.

I wonder if the graphics engine lumion 2 has a better use of hardware.

Hi Jose, compared to Lumion 1, the updated sky (more cloud types, night sky, stars & moon) will probably result in a slightly lower frame rate. The biggest impact on performance will be the new artificial light sources in night scenes. Here's what Remko wrote about that in an earlier post (the lighting system is not finished yet, and his preliminary results are based on a test scene):

The scene in the movie contains around 15 shadow maps and 3 shadow maps for the sun so that's a total of of 18 shadow maps. With a shadow map resolution of 2048 AND gausian blur on the shadow map I still got 17fps.

Regarding the utilisation of your hardware, there should be no difference between Lumion 1 and 2 when running it in an SLI configuration (if that's what you mean). This issue is on their To Do list though, so they'll be looking at ways to make SLI configurations perform faster in the future.
