Hi Chris, This really sounds like a OpenGL driver issue. W.r.t other OpenGL apps, are they opening up on both cards at one time like the OSG examples will try to do later, it could be the driver is struggling with handle two graphics cards at once.
Things you could try is forcing the apps to open up on a particular screen by setting the OSG_SCREEN env var to 0 or 1. Robert.
