System requirements for desktop computers as stated by the developer. Updated on January 22, 2020.
The system requirements are modest, but it's recommended to have a dedicated graphics processing unit for successfully playing Arma 3. GeForce GTX 775M or better mobile GPU is needed.
Most gaming laptops meet the RAM requirement of 6gb, though 4gb is enough to meet the minimum requirements.
Also, note that at least 32gb of disk space is needed, which is quite significant if you plan to install many games.
