So I've gone from ~ 10-15fps almost constantly (from what appears to be the server slowdown issue in 1.5.8.2, much like walking through treacle no chance in a firefight) but now have massive FPS drops from ~ 30 fps soon after joining dropping down to 1-2 fps and sometimes freezing completely (FPS wise, not a system lockup) after 5-10 mins. Also i completely lose sound and all control of my character for 1-2secs but continue moving in the direction and speed before it locks, this was happening in 1.5.8.3 as well.
