Good day all! I am writing to request a little guidance as I don't seem to be able to find a clear answer from reading this massive thread. I currently have the following: PE4C 2.1 750 TI Dell Powersupply Into: X220 i5, 4gb Ram, HD3000 Via: PCMCIA Now the issue I am facing is that GPU-Z is only reporting a 1.1x link. I have the latest Nvidia drivers but is Optimus working and how do I check? Do I need to install/hack to get Optimus working and opt 1.2 or have I lucked out? additionally Firestrike says my PC does not meet the requirements to run? Is this due to my processor? Any help in this matter would be greatly appreciated!!! Stewart
