God of War: Ragnarok is out on Steam and Epic Games. Although the game launched a few years after the first one (on PC), the visual quality is largely unchanged. Theres no ray-tracing or advanced global illumination tech to back up the delayed release, but Santa Monica has included a variety of upscalers.
