I am an Air Traffic Controller 4 is a simulation game developed and published by TechnoBrain in 2020. Since its release in 1998, this air traffic control game has established itself as a long seller, strongly supported by numerous users both inside and outside of aviation fandom.
The system requirements are low, but it's recommended to have a dedicated graphics processing unit for successfully running 1aaATC4. GeForce RTX 2080 Super with Max-Q Design or better mobile GPU is required.
16gb is a high amount of RAM, which has to be taken to account when choosing a laptop. 8gb is enough if you only want to meet the minimum requirements.
Note that at least 3gb of disk space is needed.
