After the patch applied on 12/12/13 I am getting major stuttering to freezing. Last game patch everything was working fine. What happened? Also the hacker/cheaters exploded. They seem to be coming out in large herds.
I'm running the following:
Windows 8.1 Pro x64+Intel i7 2600+16GB RAM+AMD Radeon 6850
Hackers? There are no hackers! Learn to play!
End of quote. Thats what I hear a lot from suspicious players (those who react too fast to someone with dead silent perk, sometimes they say "I heard your steps" - yeah, right).
But you don't have to believe a paranoid loser like me, just look at top 500 players in Accuracy leaderboards: no less than 480 (last time I checked a few days ago) had 100% accuracy with 49 999 shots (or something like that), many had negative amount of misses. Many had billions of hits, billions of misses (negative value).
Playing Black Ops I found it was ridiculously easy to find cheaters: their accuracy was over 25% (like, 30% or more). Normal players almost never had accuracy over 22%, while majority had between 14 and 18%. My own accuracy was around 20%+-2% with most guns. They also had KDs over 3, very often over 5 (try to keep KD over 5 for 1000 games, you'll understand).
Hopefully, IW will do some updates to anti-cheat engine, as it is now its next to none.
