Its the Meteor, its getting closer. I'm having the same problem tonight on Helios. Never had it this bad.
I'm starting to think its hackers aswell. I hardly lag, but earlier this morning joined a random platoon and was teamkilled a few times in weird ways like an esf crash landing into me as i was standing on a point but not exploding, soI looked up their stats and they were listed as n/a and a bunch of kills I had gotten on the opposing team was also listed as n/a within 15 minutes of 2 major lag spikes that made my game freeze and require a restart. I quit the platoon and played for close to 2 hours and havent experienced a lag since, not sure if the two are related or what, but it sure felt funny.
