Hi Mike, glad to see you back! I am also using a NVidia card, and truthfully, OpenGL isn't the best, even with 4.22. (I don't think there is a 4.5 for Vue D'Esprit. There is for Vue Pro.) It does work, but not the best implementation. I am eagerly waiting version 5, and hoping that OpenGL works as it should. Since it seems to be fixed with Vue Pro, I would expect so.
