I have a Dell XPS M1710 running Windows XP Pro SP3, with all the bells and whistles. I can play Crysis, Crysis Wars, Hawx, and others, I cannot play Crysis 2. I can see the initial video of NYC, I can see the Submarine sailing by under the Hudson River, then I can't see anything else. I can hear them talking inside the sub, but I get a black screen. Brightness is turned up. Please help. Thanx.
