Battlezone 1

title

I don't know how much processor speed is needed to run Battlezone at a framerate of 60 or higher, but the minimum and recommended requirements are here: http://www.allgame.com/game.php?id=18377&tab=sysreqs
However, 1.5 patch requires DirectX 9.0, so the requirement there is slightly higher but I assume the rest are the same.

first of you need an os which supports directx 9 like xp..vista..7...8 so if you cant run xp you cant run battlezone 1.5.
