in the demo sometimes the sould crackles. is there any thing like this in the real game or is t just my computer:confused:

I'd check your cables first. Then your pc speakers. Sometimes certain pitches in sound can't get properly processed by old speakers.

It is either your speakers or your sound card...If your sound doesn't always crakel then it miight just be your sound card...luckly the price of quality sound cards isn't very high right now so you might want to consider it...but you really might want to call the manufacturer's help line (i.e.-gateway's help hotline, etc) They will give you their opinion on it...
