Be sure to check the 'Hardware and Software' section of the BB.. So you can get an idea of what hardware this game requires to run smoothly.. These guys are really helpful, they helped me select the build parts for a AH dedicated system.. It runs wide open, with all the goodies turned on, and didn't break the bank..
I use a Sanyo 55" 1080P 120hz TV, which self adjusts the screen to the resolution, so there is no stretching or distorting of the image to fit, SWEET! And to my eye, the view is about Life Sized, I love that.. 120hz I get no lag and no ghosting, and it was just under $400 on sale at Wallyworld..
Don't forget a head tracking system, like TrakIR5, I didn't see it mentioned.. So you don't have to use the hat switch to look around.. MAJOR improvement, and really adds to the natural feel, and the enjoyment.. And survival,
