Can PS4 Pro really handle native 4K at 60fps? Well, it all depends on the game. VooFoo Studios' Mantis Burn Racing is the first game to totally max PlayStation 4 Pro's theoretical pixel throughput. So what does it look like on the Pro and just how smooth is it?
The game's based on a forward renderer which also helps in getting this game to run at 60fps in ultra HD, and in terms of visual features, we're told it's identical to both the base PS4 version and indeed the PC game. All of the more expensive visual effects make the jump across to PlayStation 4 Pro, including an impressive depth of field effect that emphasises distance and is particularly effective as background detail drops away as the circuit gains altitude. The only casualty in the move to 4K comes from the omission of anti-aliasing - you get 2x MSAA on the base PlayStation 4, while the rich pixel density and post-processing means that it isn't really required at all at 4K. Perhaps not surprisingly, PS4 Pro owners connected to 1080p displays get a super-sampled version of the 4K output, downscaled to full HD.
On paper though, the technical accomplishment here is impressive. VooFoo has quadrupled resolution over the base PS4 version, and it has done this using a GPU that only has 2.3x the compute power of the older hardware and only 25 per cent more memory bandwidth. Either the base PS4 is being significantly underutilised (in which case we would expect an improvement on its 2x MSAA) or there's something more going on behind the scenes. The team joked about 'Mantis magic' before revealing that exploiting enhancements made to the PlayStation 4 Pro GPU have paid dividends.
