Since I am unfamiliar with the Voodoo3, I googled it and came up with this: Wikipedia Voodoo3[^] None of this information is presented in your inquiry. Seeing as how you are writing your game in managed DirectX, and you don't show any of the code that demonstrates how you enumerated through the supported video card attributes, I don't really have any idea what technical difficulties you face. This from MSDN: Because some graphics cards do not support all of the features exposed through Direct3D, a mechanism is provided in Direct3D to probe the graphics hardware. If a particular graphics capability is not supported by the hardware, the check will fail, allowing the programmer to look for a different hardware-accelerated algorithm. There is a utility that comes with the DirectX SDK (Get Device Capabilities) that iterates through all the video attributes and displays the results graphically, as to whether your card supports standard DirectX operations. -- modified at 15:59 Saturday 20th October, 2007
