Contacted support at legobatmangame. They reviewed DxDiag and concluded GeForce 6150se is not a supported video card for Lego Batman. They suggested Nvidia GeForceFX 5200-5950 Forceware, GeForce 6200-6800, 7300-7950, 8600-8800, 9600-9800 Forceware. They also recommended a few ATI Radeon versions. All the action moves in slow motion, has anyone had any problems like this? Lego Star Wars runs fine on this computer. Thanks for any help someone may have to offer.
