In this article we'll examine Gears of War 4 in our usual geeky fashion. We'll test the game on the PC platform relative towards graphics card performance with the latest AMD/NVIDIA graphics card drivers. Multiple graphics cards are being tested and bench-marked with the latest cards such as the GeForce GTX 10 series included as well as Radeon RX series 400 cards. With the newest graphics cards and technologies we'll try and see how well this DirectX 12 title performs. Gears of War 4 actually is a pretty nice game, known from Microsoft and now makes its way to PC.

You are going to need a modern PC to run it as this is a proper DirectX 12 title. This shows with the recommended CPU requirement being a Core i7-4690 or AMD FX-8350. The system memory requirement for top level Gears of War 4 graphics is going to be at least 4GB paired with a graphics card in the order of a GeForce GTX 970 or AMD Radeon R9 380 with at least 4GB VRAM graphics card. Starting at that level you should be able to run Gears of War 4 at around 1080p with 40 FPS on high graphics setting. But we'll look at ULTRA quality settings, of course as we are all PC gamers right ?
