[Watch] Digital Foundry broke down the Spider-Man PS4 Pro E3 Gameplay
TL;DR: It looks good.
Sony showed off a gameplay demo of Spider-Man during their E3 2017 presentation, which revealed that Spider-Man will run at 4K with a locked 30FPS on the PS4 Pro.
DigitalFoundry broke down what was shown off behind closed doors during the event, which wasn't anything more than what was publically revealed, the main difference being that it was played live on a PS4 Pro on a high-end tv with HDR enabled. The gameplay in the live performance was generally stable, however, there were slight drops in framerate during heavy moments.
The game utilizes temporal injection, which simulates a true 4K image (key word being 'simulates'). Overall, the game looks stable - there are no pop-in textures and the shadows are stable and crisp. The animation blending and layering is "excellent" and more on par with The Last of Us and a step up from the Batman Arkham type superhero games.
There are a lot of questions left on Spider-Man like just how open the world will be beyond what was shown during E3 and whether that world size will affect the game's graphics.
