You only have 2GB of RAM though, how's your RAM usage during the game? It could be page swapping (or whatever it's called) in that area.
its like 70-87% usage. but back when i had my 9800GTX+ and 4GB ram it was slow in that spot too. although i did have a Phenom 9750 at 2.4Ghz

I'll un-unlock and un-overclock my processor and try it out and see if I get any dips in that part later tonight. Which chapter/area is it exactly?

the campaign is death toll and the level is the drains you know where you have to lower the bridge and it rings an alarm and the horde come.

Sorry it took so long to get back to you, forgot about this thread (NHL playoffs).

Tried it just now on my unlocked + overclocked processor, and I did get a drastic FPS drop. Went from the usual 90-120FPS to ~30-45.

Not sure what's causing it, and there's nothing on the forums about it that I could find.

Edit: I verified the game cache, and it said there was one file missing, which it redownloaded, I tried playing the part again and I still got an FPS dip, but it didn't go below 60. Don't know if it's just coincidence or if it actually helped.

Yes, it's a CPU bottleneck to a point. You need to increase your clock speed. An 8800GT is more than enough to max out source games, if you have the CPU behind it.

I wasn't playable on the newer source engine until I got a quad at 2.8GHz (Athlon II x4). The newer source engine really works well with more cores. But increasing your clock speed would also help as well.

It looks like your RAM is bottlenecking your cpu. 784 MHz 6-6-6-18 is really slow for a Phenom II x3, and single channel on top of it makes it worse. I would invest in some better sticks or get another stick of RAM for dual channel so you can break most of the bottleneck.

RAM speed makes next to no difference. And my rig experiences the same/similar slowdown.
