Lately I've been having 500-1k MS and wierd lag spikes while having 30mbps net. On warmane I always had good MS but now every server I play there's this high MS and wierd lag spikes and messed up my game completly. My net connection is good, downloading at maximum speed so I dont know what is causing all this? It's really frustrating and I was looking forward to play

What other things might be causing this?
