Rez Infinite - area 3
REZ infinite is outstanding. This is one title that I will also go against Analogue Processing Facility traditions and say that this game looks all the more spectacular at newer high resolutions both comparing versus the DC/PS2 original or Rez HD for the Xbox360 (whch ran at 720p). Starting with 1080p of course but it scales beautifully to 4K (and beyond technically but I doubt too many are concerned with resolutions above 2160p). It is excellently optimized, older title or not and can easily give you a 60fps at resolutions of 1440P or Higher with as little as 4GB or VRAM depending on the card.
Gameplay up until the boss of area 3. Beyond impressed with this game even knowing that it was supposed to be great going in. Such an amazing audiovisual spectacle with expertly tuned gameplay to bring the whole experience together.
I can't recommend this game enough if you haven't had the opportunity to check it out.
