Unplayable

[fmgt98]

I am having the same issue, if not the same then something very similar. An example would be when I come across a zombie, a perfect example would be in the recovery room. The game was very choppy and hard to maneuver around. Its almost like the framerate goes to practically 0.

I have:

P4 3.2 Ghz
2 GB Ram
NVidia 7800 GS (Latest drivers installed)
Plenty of free disk space.

I have the game on the following settings:

Shader Quality: Medium
Texture Quality Medium
Shadows: On
Post Effects: Off
Motion Blur: Off
Vsync: Off
Texture Filter: Bilinear
Anistropy: Off
Anti-Aliasing:Off
Depth of Field: On
Refractions: Off

Now it seems to me with the given minimum requirements, my computer should easily be able to handle this game, even at highest settings. Playing at meium settings is almost unplayable in some areas. Any other advice would be greatly appreciated.
