High End PC Gaming (i7, 1080ti , SSD ...) + A PS4 Pro for Sony Exclusives + A 4K 55inch Capable HDR TV (Sony X930e) is a Treat.
God of War is an Awesome game from a very talented developers - Santa Monica Studio nail it. 95% on Metascore based on 102 Critics and 9.2 based on 4020 Ratings. Story Line , Gameplay , Graphics and Sound. Graphics are a true masterpiece , yes Checker Board 2160p with TAA is used with a locked 30fps - the frame pacing is very good on 30fps , it is fun.
Checkerboard 2160p actually have the native pixel count of 2160p ( 3840 × 2160p , 8,294,400 pixels ) - it is a clever way much better than up scaling , where half of the pixels are projected from the previous ones (rendered) through buffers and vectors calculations. The result is a very near image quality compared to native 2160p.
It is not everything about the resolution , the IQ and techniques used in God of War textures , Shadows , foliage , HDR Lighting , physics , animations , hair physics , motion and excellent optimization set new standards for Consoles / PC games development.
Detroit Become Human and Spider Man are too promising exclusives too that will be technically powerful too.
