Left 4 Dead 2 lags in certain "spots" (PC)

[washy145]

Left 4 Dead 2 lags in certain "spots" during the games but when Im not looking in these "spots" it works fine.

my specs are:

Intel core2 quad CPU Q8200 @ 2.33GHz
Nvidia GeForce g100 3.2Gb of video memory
6gb of RAM
vista 64-bit service pack2

I play on low rez,
effects on high
model details on high
shaders on medium
anti-aliasing highest point, same as filtering.
multi-core enabled (I have quad core)
pool page memory high

Even at lowest settings it still lags at those certain spots, for me its on every level. These "spots" are at the beginning of dark carnival
the pool of dark carnival
entering the forest of dark carnival
beginning of dead center
when the fire starts in dead center

The list goes on and on and on.

I can throw a pip-bomb, tons of zombies surrounding it, it explodes and not a single drop of frames so I don't think ts my computer.

please help

and multicore that can lag you sometimes

My L4D2 runs smoothly, but sometimes my mouse starts to lag in the game.

It's the flashlight and the dynamic shadows it casts.

by the way g100 is essentially a renamed 9400gt, might aswell turn everything to low

The minimum specs call for 3.0 GHz...

...Pentium 4.

Definitely lower AA. That should let you raise the resolution a bit, too.

tl;dr dumbass? he said that the servers lagged and posted 2 by accident. It wasn't his fault.

Lower AA, If not, turn off v-sync.
