Do not waste your money on SR2, go with SR3 or SR4. With SR2, the farther away your computer is from 3.2GHz in either direction the faster the in-game speed is. So, the passage of time, animations, character movement, etc. Yet the game is not running any faster in terms of FPS. IIRC Red Faction Guerrilla also had this issue but it was fixed in a patch. SR2 for PC only ever got 6 months of support and things never got officially fixed. There is actually a third party fix but it involves a lot of trial and error to find the correct value. so I guess that is a non-issue.. :/ Also, there are just slowdown issues in general, I do not recall if it was the fault of not having a fast enough disk, but when you have a then-modern 7200RPM drive you expect it to work decently. I do not remember if this ever got fixed, but I was certainly not using a slow PC and I am not the only one to have that issue. I *think* there was an issue when playing coop where between missions one person or another would get booted.. idk. Even with it's terribad old console-port graphics it still would have been a great game if there were not so many issues with it.
