constant lag/stutters?

problem seems to have gotten worse after the recent patch....

-playing on the appropriate server for my region
-averaging over 100fps
-ping average is 35ms, when I do some data logging on my connection while playing there are zero lag spikes, disconnects, timeouts on my end
-CPU is not overloaded/running at 100% usage during game play
-GPU is not under utilized and is at 99% usage during game play
-system RAM and VRAM are not overloaded
-system drivers are up to date
-wired (1Gbps) or wireless (866Mbps), no difference

some people in global chat said its tied to chat, having global chat turned off or on make no difference, same with the /clear or /cls commands a user recommended

is there a a fix for this?

Looks like some problems on server side after recent patch. I see huge latency spikes and then often freeze with huge latency and then dc. After relog I see no portals and need to start map again (so it isn't simple dc, instance crashed on server side?).
Checked few regions - the same issue.
There are the same complaints in other thread.
