Display issues with nvidia quadro graphic cards

Dear Unity fellows,

I have a really weird issue with my game, I can’t find anything about it here in the answers or in the forum.
While my game OFabulis (http://www.ofabulis.fr) displays just fine on most computers and macs, it doesn’t work at all on pro graphic cards (nvidia quadro). The GUI is no displayed, as well as the 3D stuff : the content is all grey (see screenshot below :-/ ). But by the sound, we know the game is working. Only display issue then.

There are shaders on some objets, but not on all of them (not on the characters for instance), so I guess the problem is not here.

In addition to Unity pro, we are using Ulink networking suite for the multiplayer part and a plugin for the interactive videos (AVPro Quicktime). I don’t see how they would interact, but…

Does anyone had this issue before ?

Ok, simple enough finally… The grey screen was caused by AVPro Quicktime. It didn’t manage to launch. For it to works you not only have to install Quicktime but also reboot the computer (yep, that easy). Not related to Nvidia Quadro in the end !
