Before the patch i could set all the graphics properties to high and have everything on except for ambient occlusion and maintain an fps of 35-50. After the patch, no matter what I have the graphics set to (everything at high and everything on or even everything on low and off) I get about 35 fps when there is no action on screen but as soon as i get into any combat the game drops to 19-21 fps.

In case it helps i have a nvidia gt 540m, an intel core i7 2630qm, and 4 gb RAM. Are others experiencing problems like this?
