S.T.A.L.K.E.R.: Call of Pripyat

I've played through Shadow os Chernobyl and Clear Sky multiple times, and they were great... but only with weapon mods, since the default is always a joke, you can't hit anything further 50 meters with an ak47, while skilled men can accurately shoot with it to 300 meters irl. But for call of pripjaty there isn't any weapon mod that not causing CTD(actually i didn't found any mod that not causes CTD while i played SOC with the great Oblivion Lost mod) so the firearms are crap, it would be better to use swords and things like this for such close combat. Also the optimization is very bad, the game looks badly on high graphics but still runs badly. I regret that i spent even 7 eur on it, it not worth a single cent
