Did you use a 4gb patch? iirc, using a 4gb patch fixes this and you'll pass that section without issue. This one from the TechPowerUp forums is the one I like because it allows you to undo it later if you want to, unlike some others that are more basic:

Edit: btw, just an fyi, but if you wanna successfully use a 4gb patcher on the base game, you have to run the exe through steamless first to remove the steam stub drm -- if you run a 4gb patcher on FEAR without removing the steam drm first, you'll get an error when trying to run the game. Steamless isn't need for the 2 dlcs as they don't have this drm built-in, only the base game exe does.
