This is a truly amazing game but unfortuately, it has some real problems that cause it to crash periodically. After about twenty minutes of gameplay, the software locks and Windows tells you that "Crysis has stopped working". I am running the game on a brand new Dell Inspiron 620s with 6Gb of Ram and it locks up about every twenty minutes.I strongly urge potential buyers to read all the reviews on this game (Amazon and other game sites) before purchasing. I wish I had done the research.
