Love Wow Gold and Love Powerlevel

Having experienced extreme lag--in excess of 1000ms--on the PTR with patch 2.2, I merely figured it was the server succumbing to its high population. But now that the patch is live, where as I used to sit around 60ms, I know hover at about 1200ms.

To make sure it wasn't a patch day coincidence, I logged into WoW from another computer running Windows--it worked fine. So I launched WoW through WINE, and I experienced no latency issues. The problem only occurs when I run WoW v2.2 from within Cedega.

Is anyone else experiencing extreme fits of lag since the new patch has gone live? And moreover, is there a solution?
