I have a Dell XPS 8500 computer with an i7 processor (3.4 GHz) 16 GB of 1600 Ram and a 660Ti video card. I run the system on three 40 inch samsung TV's. I could get both 2D and 3D before I added service packs sp1 and sp2. I need these addons to run Megascenery 2.0 and Chicago. After I added the service packs I lost the 2D panel. Help!
