Here's a list.
1) Try to make the matchmaking to match people from the country we play, not from other countries. Example: Search preferences--->Any, Normal, Best.
2) Rent some servers. It is impossible to play this game with so many hosting problems, the best connection i had was 3/5 bars and still the game it's unplayable guys. Most of the times is 2/5 or 1/5!!! And not only me, i've seen many other people on the lobby, yesterday i played a game and all 12 of us had 1/5 bars! All of us!
3) Sound issues. The sound is horrible, some times we dont have sound at all, especially on Kill Cam's. We see the gun fires first and after 1-2 sec. the sound is working.
4 Frame drop. Im not so good on the frame per second thing but this game has a serious problem with that, i know its not a Hi End PC but the game with those fps on PS3 i dont think its gonna last long (hope im wrong). It's very dizzy some times, expecially on big fight's.
5 Bug on the Hunter mode. When i start a round i see for about 2sec. just the guns of my team mates moving. This only happens for the ''Cell''.
Please everyone feel free to add any other problem u found, this list is gonna keep updating...
Crytek please, i stopped playing Crysis 2 because of the host problem. Please try to fix that.
Thank You
