I can't even play because I have an AMD Phenom II processor which has NEVER caused a problem with all of the other high end games I play. I had given Bungie until Friday to fix this before requesting a refund. However with all of the problems with running a chat program which consoles have available to them I'm requesting a refund right this very minute and don't think I will pay $60 for a headache and a stupidly ruthless company that doesn't even know how to make a game work in PC.
