Woo boy. What can I say? Since the Dec. release came out, I've gone from 50-60 FPS to 10, 12 FPS, 20 MAX. 
Standing in Pocket D, I "Lost Connection to MapServer" 23 times in three minutes. 
I recently upgraded my mobo, reinstalled my OS fresh, installed new drivers for my vidcard, did a clean install of the game... in the week or so my PC was on blocks for rebuild, that's when the latest version came out. And on an upgraded PC, I now get half the framerate I did.
Before I reinstalled, I was starting to lose interest in CoH, because I encountered a terribly frustrated gameplay 'wall'. I figured once I rebuilt the PC, I'd be fair and give it another shot. Maybe I could enjoy it once I figured a way past that 'wall'.
So I get back to the game, and I get 12 FPS. 
It's a slideshow.
It appears to me I made a mistake being willing to give CoH another shot. I doubt you'll have it fixed before my little remaining patience in the game's problems runs out.
For reference, I proved it's not my PC today by running vidcard-intensive games at 60FPS. Half-Life 2 at 1024x768 with 4xFSAA on a Geforce 7600, 2+GhzPC, 1GB RAM. 
The only thing giving me poor performance is CoH.
