It's kinda the same, a hit and miss. I have constant lag issues, sometimes manageable but often unbearable. I've been having problems since patch 1.03, nothing but instant deaths, core feels like like hc when it comes to dying.
I just turned the console off, i couldn't take it anymore. I've been getting gold on the Five-seven for several hours today, first racking up headshots and just now finishing the unlocked camo challenges. Earlier today i got into a game of TDM and went on a 20 gun killstreak using only the Five-seven without attachments. I didn't have lag advantage, it took me between 6-10 shots per kill, i just outplayed the **** out of them. Then more and more people started getting online, and the lag got out of control. In the last 5 lobbies i was in i couldn't break even or barely broke even, 15 shots on average per kill, instant deaths.
It's been like this since 1.03, lag is always there but sometimes it's just totally out of control. The game always plays better when there are less people online, dxp has been a lag fest every time. I still need 75 kills without perks and 3 double kills with Five-seven, the combat knife is still missing around 100 kills + whatever camo challenges unlock, and my assault shield is still 3 lvls away from max level but it's golden. Other than that i've done all mastery and camo challenges to every weapon in the game. I think it will be time to put the game down as soon as i'm done with the challenges i mentioned. If it stays like this, i'm not getting DLC. I've also been a prestige master for more than a month now, so there's not that much left i'd like to finish.
I know the latency issues will not be fixed, but if we could get closer to how the game performed prior to 1.03 it would nice to get the DLC and enjoy my diamond camos in new maps.
