OK, just a few warning for the people that are interested into buying IV for their PC.
First of all u gotta have at least an ATI 3xxx series or higher (sorry dont know much bout Nvidia) and at least 2g RAM to play Medium settings.
There are still alot of bugs, such as textures appearing in and out constantly and lags.
There are some fixes such as for the Fatal error RMN20 u can simply run in compatibilty with windows 2000.
If your game wont let you adjust your settings the way you want it, simply make a notpad called: commandline.txt
add this to it: -norestrictions. If you read through your readme u will find some more commands.
I will add more info later as for now im tired
