When it comes to playing machine-intensive games, such as Silent Hunter III, should one do something first to dump the system load? That is, do you need to shut down programs (like anti-virus programs) to free up the machine to handle the game? If so, what all needs to be shut down? (I heard this advice once).
Could this be a problem affecting the freeze up I had last night?
One can see why many favor the platform games where computer capabilities and loads are not a factor.
