layed the demo on PC and PS3.
PC (Core2Duo E6750 @3.0ghz, GTX 260 MAX CORE, 2GB RAM, VISTA 64) version runs on MAX settings with 4xFSAA and 4xAA details on my PC at 1920x1200, though the game defaulted to 960x600.
60 FPS most of the time with some dips to 30 FPS, with vertical sync on. With it off the game runs 65-90 FPS and doesn't drop below 50FPS. Go figure.
I get the micro stuttering as mentioned by others, it usually happens when the game is accessing the HDD. This might be because I am running it on Vista at the moment and there is only 2GB RAM in my machine. And/or when the game is saving checkpoints.
The PS3 version doesn't look as good for a start, the textures aren't as details and sharp and the game defintely suffers from running at a lower resolution without FSAA. It also suffers from slow down in the same places as the PC version. Plus the PS3 version isn't nearly as playable with a gamepad compared to the PC's keyboard and mouse combination.
As for the gampeplay, this IS a FEAR game, no doubt about that. It's very atmospheric and scary, but it's also very linear, just like the first one. In fact I would go as far to say its the same game with better graphics. Now for me thats not a bad thing, I enjoyed FEAR an will probably enjoy this one.
The slow mo combat is very satisfying and you are constantly moving forward and not getting held up by puzzles. You can also flip up tables and the like to act as cover during fire fights.
As for the complaints about it being a console port, I just don't see it. a lot of games use on screen prompts to tell you which keys to press to perform a certain actions. Half Life 2 did it and no one is saying that was a shoddy console port.
If anything I would say the console version is a shoddy PC port. The graphics are worse and the levels take longer to load. No doubt the PC multiplay will better, hosting more players and any developer content being released to PC owners for free. I didn't realise that PS3 owners of COD 4 had to pay £8 for what turned out to be patch 1.6 of the PC version.
The PC version also runs a nice little applet for G15 keyboards, you get a HUD for armour, health and ammo running on the LCD. Nice touch I thought.
