Actually, if you havent already, try experimenting with your computers screen resolution settings.
You have some in FS, and more in your graphics card/desktop settings interface. (Some graphics cards will need you to download their 'tuning' controls for specialty fine tuning).
You can boost your resolution up very high, say over 2,000 pixels wide, work with Anisotopic settings, etc, to really dial in a photo real screen view.
But, you will start to have slower performance.
Having a good deal of RAM (like 3 gigs or more) and a good graphics card is your first requirement, then work your settings. Extreme settings on a low performance computer will still avail you a great view, but extremely slow performance.
There is a balance though. You can usually bring up your visible settings quite a bit before touching the performance balance.. at which you simply back off your settings...
