2K Games plans to release PGA TOUR 2K21 on August 21st on PC, PlayStation 4, Xbox One, Switch and Stadia, giving gamers less than two weeks to prepare for the game's launch. On the game's Steam page, PGA TOUR 2K21 now has a complete set of PC system requirements, allowing PC gamers to judge whether or not their PCs are ready to run through 2K's selection of licensed courses and handle the game's "slick graphics" and simulation systems. New to the series is the game's PGA TOUR Career Mode, which allows players to become the FedExCup Champion if they can surpass the skill of the game's PGA TOUR Pros. 

On PC, gamers with strong quad-core processors, such as an i5-769, over 4GB of RAM and a DirectX 11 graphics card that's stronger or equal to an HD 5770 will be able to run 2K21. That said, 8GB of RAM, AMD's HD 7850, or Nvidia's GTX 660, and an i5-4670 (or better) processor are recommended. Storage-wise, PGA Tour 2K21 will require 12GB of storage space, and the game will require a 64-bit Windows 7 or newer OS to operate. Given the age of some of this game's recommended hardware, it is likely to all relatively modern gaming PCs should be able to run PGA Tour 2K21 with ease.
