Metro: Last Light Frame Rate Problems

I recently bought Metro Last Light and I haven't been able to actually play through it because It is running at around 15 fps. At first I thought that it could just be that I needed to lower the settings because I was originally running the game on the highest settings but, when I lowered the settings to high, medium, and low, the game would sti only run at 15 fps. Is there any way to fix this and is it possible that the gpu drivers are at fault.

Do you have the latest drivers? I know it had problems at launch with fps but that was solved not long after by a driver update.  I assume pyshx is off?

Now I just feel dumb. I hadn't turned off PhysX so that's why it was running so poorly. Thanks you
