Anyone still playing?
There bloody ARE dedi servers you nutters However they arnt ranked, as BloodOmen says, but does that really matter? Really? Only real issue is you have to use your set up for a private match, so you cant have 4 or 5 different classes, just one specific and use the other defaults, so BloodOmen is talking bollocks there.
You can fix lag compensation - seta cl_packetdup "0" , but remember to set your config to read only or it will get wiped.
Am I still playing? Clearly yeah
Ranked servers matter yes, not all of us like having fuck all to show for hours upon hours invested into a game, those times are in the past (long long long in the past) so in hind sight the dedicated servers available arent fit to be called dedicated servers, Black Ops had dedicated servers right - Modern Borefare 3 does not, simples.
As for the LAG if someone has a shit internet connection or is downloading mountains of tree elf porn its going to fuck with hosting, no amount of config tweaks are going to fix that.
