[EDITED] Hard lag problem...

[WoNHommer]

Well, every map that have an enemy lags HARD. I mean HARD: less than 1FPS, and I can't play... It lags some times during the game, but it still playable. The menu works smooth... Its not my config, I have the specs:

P4v533-MX
P4 1.8GHz
512mb DDR400
GeForce FX5200 - 256MB

Every setting is set to the lowest, the quality of the graphics is awful, so is the lag...

Thank you, I will play it when this problem is solved

EDIT Now it lags every time I load the game... I can't continue playing...
I set every setting to the best, and the lag is exactly the same, but the graphics are much better...

I am here:


It's right after the door where you have to pull a lever and run to pass to the other side. Here's a screenshot of that door:
