TomTuypens,   The latest driver I see available for 2008 R2 is located here.    Let me know if this helps.  
Dear community, In our factory, we are running Windows Server 2008 R2 SP1 on a Dell PowerEdge R150. For one of the applications, Vivotek Camera software, we need to upgrade the driver for the graphics card. It's a Matrox G200eW, that is integrated in the motherboard. Current version on our server is 1.1.3.0 (27/07/2009), and we need to upgrade so that it provides OpenGL 2.0 or higher. Matrox suggested we get in contact with Dell, because that is the system manufacterer. Can someone help me get the latest driver/information ?   Thanks in advance
