But, according to the developers, for the best experience they recommend a graphics card equal to or better than an NVIDIA GeForce GTX 760.
The game can be played on integrated graphics such as the Intel HD 4000 series. An Intel Celeron J1800 CPU or equivalent is required at a minimum to run ETS 2, but the developers recommend a CPU greater or equal to an AMD Athlon II X4 640. Additionally, the game developers recommend somewhere around 6 GB of RAM in your system.
Euro Truck Simulator 2 system requirements are pretty low, due to the game initially being released back in 2012.
