yeah it happened to me a lot last night/two nights ago when I was playing with JDM. But today it was much better, I wasn't lagging or doing any of that crap at all. It felt like the mic communication were also shitty.
and I know for a fact it's not my internet that's causing this... http://www.speedtest.net/result/1628451373.png

my theory is, some people said they weren't gonna play BF3 until they patched some shit up, so I'm assuming after the patch a shit ton of people got online. idk. whatever it is, hopefully it's fixed now
