Authentic, diverse, open - Arma 3 sends you to war.
System requirements for desktop computers as stated by the developer. Updated on July 8, 2020.
The system requirements are modest, but it's recommended to have a dedicated graphics processing unit for successfully running Arma 3. GeForce GTX 660 or better GPU is needed.
Most gaming PCs meet the RAM requirement of 6gb, but 4gb is enough to meet the minimum requirements.
Also, note that at least 32gb of storage space is required, which is quite significant if you plan to install many games.
