As detailed earlier in the PC features trailer, Ghost Recon: Breakpoint will have "full PC optimization" with unlocked framerate, rebindabled controls, multi-monitor support as well as support for ultra-wide resolutions. It also has support for AMD's FidelityFX technology, which will add sharpness to the rendered image, as well as both support for Tobii eye-tracking technology and an integrated benchmark.
According to listed PC system requirements, you'll need at least AMD's Ryzen 3 1200 or Intel Core i5-4460 CPU, paired up with 8GB of RAM and either an AMD R9 280X or Nvidia Geforce GTX 960 with 4GB of VRAM, to run the game at low settings and 1080p resolution. If you are looking for high-settings at the same resolution, requirements go up to AMD Ryzen 5 1600 or Intel Core i7-6700K, 8GB of RAM, and either an AMD Radeon RX 480 or Nvidia Geforce GTX 1060 (6GB) graphics card.
Ubisoft also released requirements for ultra setting at 1080p, 2K and 4K resolutions, starting with AMD Ryzen 7 1700X or Intel Core i7-6700K, 16GB of RAM and either an AMD Radeon RX 5700XT or Nvidia Geforce GTX 1080. The same requirements will get you to 2K/1440p resolution at the same ultra-settings, and if you are looking to play it with all the bells and whistles and at 4K/2160p resolution, you'll need AMD Ryzen 7 2700X or Intel Core i7-7700K CPU, 16GB of RAM, and either an AMD Radeon VII or Nvidia Geforce GTX 2080 GPU.
As noted, the game will launch on October 4th while the Beta is expected to launch on September 5th, but only for those that have pre-ordered the game or for those part of Ubisoft's Uplay+.
