Force a video resolution / aspect ratio?

[hellstudios]

(sorry about the other thread in general discussion, please delete it)

Hey all, I'd like to know how to force a resolution in amnesia to 4800 x 1200, since i have three monitors and cannot set the aspect ratio in the settings to 16:9 like i do with other games using Softth, my main video card is a 9800gtx+ and my secondary is a 7200gs, I usually have no problem with other games using softth, but i cannot seem to find the aspect ratio in the settings.


also, Holy crap, I have to force myself to play this game. I'm still in the jail part D: I guess i'm not good at horror games, ha

OS: win xp sp2 64bit
is the log really needed for this type of problem?
