Project CARS 2 is shaping up to be one of the best-looking games of 2017, but even the new and powerful (at least for a console) Xbox One X is coming in November, can't run Project CARS 2 at 4K, let alone 60FPS.
Dutch website GamersNet had some words with Slightly Mad Studios' Game Director, Stephen Viljoen, said that Project CARS 2 would be running at 4K and 60FPS on Xbox One X. But it looks like this was a big of a fluff, and something SMS' Ian Bell said was a "misquote". We don't know what Sony's refreshed PS4 Pro will run the game at, but I'd say 1080p 60FPS would be a safer bet.
Slightly Mad Studios' Ian Bell posted on GTPLanet's forums, where he said: "Yup, this was a misquote. We're running sub 60 FPS at 4K and we'll probably always be unless we drop livetrack and a host of other things... We'll probably upscale from something very reasonable". Bell wouldn't comment on locked 60FPS at 4K on Xbox One X, adding: "We don't like the term 'locked'. It would put us in first party territory where chest beating is more important than a great experience. We'll be 60 most of the time in normal racing and we'll push the consoles to and beyond their limits for more interesting racing. Even if that means dropping a few frames".
