Runs A LOT slower than BF2 for me. I get great frames at 1920x1200, 4xAA/16xAF in BF2. Performance was lackluster in Fear for me. At 1600x1200, everything set to high, no AA/but 16xAF. No soft shadows on. I was getting between 25-50 frames. Sometimes more in very dark areas, etc. I didnt play much, to get into much action, so it could dip lower than that.
I am getting tired of these new graphical effects, that cant be used with older, commonly used, and very much liked effects. Cant use softshadows with AF? Ugh. One thing is pretty funny, the readme says to not play in any other res than 1024x768 with ANY card out today.
One thing is for sure.. this game is going to be scary. The first 2 mins of gameplay, its already scary. I dont know why, but that little girl is scary... I keep on telling myself its a game, but its like a movie, it can still scare you. Her shadow, her giggle,
