I had a few mods installed, FOOk 2, weapon mod kits, felltout, eve(with fook) but thats about it. I seemed to freeze a lot when travling in the metro tunnel, stations. I changed the service pack to 2 (on windows 7) and changed that one line of text in the ini file, blue thread or something. that cured the freezing at the beginning tutorial part. But was just wondering what else could cause this? I've uninstalled FOOk 2 and kept the rest, going to see how that plays out.
