PS5 Tech Demo Detailed, Called 'Hugely Impressive'
More rumors emerge about the PlayStation 5's graphics capabilities.

One such rumor has started a fervor of hype with a user by the name of Kleegamefan giving a first-hand account of a demo for a game that is being developed for the PlayStation 5. For the sake of transparency, it should be made perfectly clear that this is a single, alleged description from a mostly anonymous user, but it would seem that the rest of the users on the forum believe the initial report.
According to the post, the game that Kleegamefan saw the demo of was so visually stunning that it's difficult to put the quality of the graphics and physics engines to words, thanks to both the game's engine and the PlayStation 5's incredibly powerful SSD. From a number of replies, one of the most impressive feats of the game seems to have been the way that the game engine casts shadows, allegedly casting individual shadows from each leaf of a small bush, intricately expressing the movement of every branch and leaf as they swayed in the wind. This has led some commenters to speculate that these types of effects are achieved by ray-tracing, but if the claims from Kleegamefan can be believed, the effect is an incredible sight, almost unmistakable from watching live footage of foliage blowing in the breeze.
Kleegamefan also stresses in their posts that the demo they saw was unfinished and the astounding experience with the game is far from being the shipped project. For some players obsessed with framerates and resolutions, it may be disappointing to note that the game was running somewhere between 25-30 fps, although the resolution was reportedly 2160p and considering that this was an early demo, it is possible that the finished results will come closer to 60 fps in the future. Either way, Kleegamefan sums up posts best by stating that it likely won't be the specs of the PlayStation 5 that will blow expectations, but the quality of the games that will capture audience attention as more information comes to light.
