Free disk space 30GB Internet Persistent broadband internet connection Notes * On systems with NVIDIA GeForce GTX 775M, GeForce GT 755M or GeForce GT 750M graphics chips, we have confirmed that a display issue occurs when continuously changing the screen resolution. This is directly attributed to an issue with the drivers for these graphics chips. We are currently investigating this matter with NVIDIA, and are working with them to have them address this issue. Until they have released a fix to address the issue, please avoid changing the screen resolution continuously. If you encounter this issue, simply restart the game to resume normal operation. * Specs are subject to change in the future. * While we have confirmed operation of the game is possible on the MacBook Pro, due to extraordinary heat generated during gameplay, we have taken the precautionary measure of not adding the machine to the list of applicable models. Your understanding is appreciated.
