You are not gonna stop are you? Okay...I asked one of my online friends; best friend actually, who plans on visiting Pakistan just to meet me. I put forward this question, that it is impossible to run Crysis 1 on PC, so why? Yup, we are chums, and here's his response; Well, in regards to your question, there are several factors to consider i.e. the type of hardware, the configuration of the hardware which Crysis is running on, how optimized the hardware is, the optimization of the software in question (Crysis) and whether or not there are software tweaks and mods installed to run Crysis.
Ironically and just for future reference, the current machine I have running cost me more than $4,000 and yet, I was unable to run Crysis on max. The reason for this was due mostly in part because Crysis is one of the most inefficiently coded games of the last decade.
