For people who love musty old sofas, smoking rooms and well worn slippers, there are few greater thrills in life than the arrival of Hearts of Iron IV. Paradox Development Studios' tactical grand strategy series set during World War II has proven an alluring pull for armchair strategists worldwide, allowing players to dictate and alter the events of the largest conflict the globe has ever seen.

Hearts of Iron IV ups the ante over its predecessors with a graphical and UI redesign, from which players have total control over one of the most authentic real-time war simulations around. Paradox have promised HoI IV will be the most accessible in the series yet, all the while supporting better AI and totally free-form sandbox-style gameplay. Before the Blitzkrieg commences, however, be sure to cast a tactical eye of the official Hearts of Iron IV system requirements. 

Hearts of Iron IV Minimum System Requirements

  • OS: Windows XP 32-bit 
  • CPU: Intel Pentium 4 2.4 GHz or AMD Athlon XP 3500+ 2.2 GHz

For those of you who spied the Stellaris system requirements earlier today, these requirements for Hearts of Iron IV may be eerily familiar to you. They are in fact the exact same system requirements. Pretty much all of Paradox Development Studios' games run on the same Clausewitz Engine, designed for grand strategy titles. As a result, you can expect all system requirements for its games to be broadly similar. If you've got Europa Universalis IV and it runs ok, then you'll be fine with Hearts of Iron IV.

If you haven't played any of Paradox's recent games then rest assured, Hearts of Iron IV isn't demanding at all. This World War II strategy game is real-time but it isn't fast paced, so a high frame rate really isn't a priority here. In terms of the specs you'll need, these are once more right at the lowest end of the scale, so Hearts of Iron IV should be capable of running decently on all but the most ancient of PCs, ie more than 10 years old. 

We are looking at perfect laptop fodder here for the HoI4 system requirements. The CPU and memory demands are low enough that Hearts of Iron IV should run on most notepads, provided they have a semi-decent level of integrated graphics of an extremely low-end dedicated graphics card.
