Simply judging from screenshots? I think i can trust my eyes on this one. This isn't the first 4K game i'm playing. As far as i know the game renders at 1800p and gets upscaled to 4K. I don't know if they use checkerboarding. Maybe we have to wait until Digital Foundry finally covers the beta. However, i heard some people complaining about jaggies with the standard PS4. I haven't noticed much jaggies on the Pro, it would go as far as to say you won't notice them on a 4K TV at all. And i have been through the jaggie hell in Forza 6 so yeah, i'm sure i would see them.
The most obvious reason the beta does indeed benefit from the Pro and renders at 1800p/4K is the fact that Polyphony and Sony showed the game in 4K and running on Pro on many occasions, already, the VR mode for example has been shown on Pro and GT Sport has been one of the flagship titles for the Pro and it's 4K gaming for a long time. In my view, it is highly unlikely the beta doesn't offer Pro support and after spending so many hours with the game i would pretty much rule that out.
Not sure if serious. Lol
I'll try replying as best as I can, because you probably don't know much about resolution/checkerboard rendering/how Digital Foundry works.
Going by what PD told us, the final game will render internally at a native 1600x1800p resolution. This will be checkerboard-rendered to 3200x1800p, and then upscaled to a 3840x2160 image with some simple upscaling algorhythm.
Checkerboard rendering it's pretty easy to spot if you know where to look.
IF the beta 4K screenshots posted by users so far are true 4K screengrabs taken from a PS4 Pro with a 4K panel, then the beta is rendering at a 1080p resolution upscaled (badly) to 4K.
Example:
this 4K screen. If you downscale it to 1080p it'll become pixel-perfect. If you upscale it back to 4K, it'll be almost identical to the original. Upscaling algorhythm might be different (bicubic, trilinear, who knows) but the pixels are roughly the same, meaning the original grab was upscaled from a 1080p buffer.
If you wanna find out how Digital Foundry figures out the resolution of a game, check
this video (answer: from screenshots).
Again, since you have a Pro with a 4K panel, please post some screenshots. I'd trust your grabs more than grabs taken from the internet.
As I said, 4K screens of the beta are rare - and who knows, maybe PD added Pro support in 1.04
I've spent enough time on dumb console war threads (
) to know how to pixel count, so it'll be pretty easy to check.
