in FA , it could work but you'd have to have area behind you rendered at very low graphic setting. so you could still play if for some reason you do a 180 faster than it would have time to render.
I know the source engine is also great for allowing you to not render area hidden behind walls / aren't in line of sight. http://www.tophattwaffle.com/hammer-tutorial-v2-series-21-optimization
Idk how gamebryo works but these are the things this game needs.
things within 12 feet of you could be well rendered all around or at least medium quality behind you.
