I first bought OFP off the back of one of the many excellent reviews around its release date. Unfortunately, my laptop didnt have a graphics card, but knowing next to nothing about computers at the time, this didnt deter me.
I had to play the game on the lowest possible settings, and visibility on my 14" TFT screen was next to nothing, especially in the dusk/night missions.
To be honest, I thought this was designed into the game just to add to the "fog of war", i couldnt see enemies over 75m away, but i still loved the game and managed to complete the campaigns (including Red Hammer) relatively quickly (despite struggling for a while on After Montignac, as we all did!.
Anyway, i think this is the ultimate challenge, playing on a platform that is hopelessly out of date but just manages to play the game. Resisitance was simply too much for my laptop, but i now enjoy OFP on a beautful 19" screen, and with a graphics card!
