Hi,

I know Lumion request to use the card 970m ...

my question is whether Lumion viewer requires the same graphics card?  ???

is that I can use a laptop with 960m graphics card to Lumion viewer (small and big projects)

thank you in advance

Hi IP_jeanlo

The Viewer does not require the exact same graphics card (that was used to make the scene), in order to play the scene.

The Viewer itself will play on any device meeting Lumion specifications.  It's the scene that will determine successful playback.

So, the demands of the scene from the content and the effects used, could cause a lessor capable graphics card to result in poor playback (FPS).  For example if lots of Reflection Planes are used in combination with Spotlights etc.

So it's a good idea to either test on the same type of hardware or something similar if possible. 

If not possible you can check on the PC that made the scene and get an idea of how well it might play on some other device.  You can do that by either:
1. Running the scene in Play Mode (Theatre).  So for Movie Playback, press the Play Preview button then Play (Theatre) button.
2. Installing the Viewer and opening the LS5 scene.

A (GTX) 960M card is quite a bit less in terms of performance than a 970M card.  The 970M has a Passmark of 4573, whereas the 960M is only 1576, i.e. less than the minimum requirement of 2000 Passmark points (for simple scenes).  So some scenes might play on the 960M, some might start to lag or show low FPS if there is more content or demanding effects used. 

Note that it's possible to perhaps create a Movie Set (set 1) specifically for Viewer playback on other (and also some lessor) devices by copying the clips from some other Movie Set, and then reducing, turning off (hiding), or removing some of the effects that might be more difficult to playback.  Alternatively if the scene is finalised, you can make a special scene version, saved under a new scene name, just for the Viewer.

OK thank you,

Hi IP_jeanlo, the 960M does not meet the minimum requirement which is 2,000 Passmark points (for simple scenes), so as Peter mentioned, the performance (framerate) will be poor and you may encounter artifacts, regardless of whether you remove the Movie effects or not. In other words, we recommend that you use a more powerful graphics card which as a minimum is compliant with the system requirements.
