First of all, I've been playing the retail version for about a week now, it's steam-based and given out to review the game for the PC.
I've read some comments about the game pausing. I've noted the same thing to some extent, but it usually only happens when saving and/or loading new content. Throughout normale gameplay, firefights etc, I've noticed no stuttering/pausing. In the EPA I've also noticed no pausing at all. Besides that, I'm not very sensitive to the widescreen issues or the film grain filter. Maybe I'll try fixing it and see if I really notice a difference.
So, if those two are your biggest complaints, I wouldn't worry to much about it. The gameplay is pretty good, at Hard it's enough of a challenge, but doesn't have you loading savegame all the time. The different enemy's are also pretty cool, with only the puppetmaster being a bit dissapointing, all he needs is 500 rounds, but he barely deals damage. The spectres can be really creepy, and with Alma jumping you out of nothing, this game will have you on the edge of your seat quite a few times. I particularly like the cloaked enemy's, who jump all over the place, including the ceiling, ninja-style, and if you don't watch out, they'll quickly get the best of you.
Performance wise this game runs very smooth. These numbers are with a single HD4850, oc-ed to 700/1100, with 4xaa/4xaf @ 1680*1050. Sure it's no Crysis, but for this horror-like FPS it works just fine. All in all I'm looking at a favorable review.
