I've reinstalled the original FEAR and boy, you can really notice the graphical upgrade of FEAR2. Not only does it look much better, it also seemingly runs at twice the FPS for some reason.
Still, I'm having a lot of fun with FEAR1. Fucking gunplay gives me boners. First playthrough of the FEAR2 demo didn't leave me with that feeling. But a second play through gave me more promisw.
