Actually alot of games are around 1800p... from what I remember reading.

It's looking more and more why the PS4 slim has not sold as well as it should because consumers are waiting for the PS4 Pro. These screenshots of justifying their wait and gamble. Maybe I should pre-order my PS4 ASAP and not worry about a bundle.

PS4 Pro is looking like less of a meme, pretty noticeable differences in the pics. I just wish there were bundles. Going to hold out until end of November in hopes of an FF15 bundle.

color me impressed

When you do it like this the difference is enormous, but if you just look at the OP and don't change the size of the images there the difference is very small.

I am confused. What is the truth??

Also, I hate when people don't provide the original source for the material in their threads. What actually means "PS4 Pro downsampled image to 1080p"? Is that a screen capture of a true PS4 Pro running Titanfall 2 at 1080p, or is it a screenshot of the game originally running in 4k but downsampled to 1080p in a photo editing program?

And how come that in your post, the right picture is named "720p - 1000p"? What is it that we see actually?

In your edit you change your wording to "downsampled" instead of "supersampled", but isn't the term supersampled actually correct? I thought that's exactly what the PS4 Pro does when you run games on a 1080p monitor - the PS4 Pro internally renders the games in a higher resolution (I don't know if it's literally 4K or 1800p, but at least the resolution is much higher than 1080p) but then supersamples the image down to a 1080p outputted image.

I'm not saying it's wrong to call the process downsampling because the technique is traditionally called downsampling too, but I thought supersampling also is correct. They're actually the same thing?

What do you mean by "don't change the size of the image"? The comparison i have there is just cropped, the pixels themselves are 1:1 with the original (no zoom). I cropped them to allow for a better comparison, since VGC squishes images down to fit into the thread, and so i could line up a similar section of the image.

I can't give a definitive answer to the second point, but it should look similar regardless to if it's downscaled by the console or an editing program. It'd be surprised if the Pro is apply much (if anything) in the way of post-processing while the image is being scaled down.

As to your last point, TF2 runs at a dynamic resolution, with 720p to 1000p being the range in which it moves. I can't be certain what the exact resolution in either is (since both are scaled to 1920x1080), so i put the full range for the standard version (with a note that i think it looks closer to the 720p end), and added a ??? for the Pro version since at the time we knew nothing about it's range, or technique. 

You're correct, downsampling and supersampling are functionally the same thing. I was very tired when i posted that, and thought i'd put multisampling. It seems i made a mistake in correcting my mistake :p

the difference is huge

Digital Foundry found the game runs mostly 1440p on the Pro. This is the supersampled resolution to 1080p. So,

PS4 -> 1000p upscaled to 1080p

PS4 Pro -> 1440p supersampled to 1080p / upscaled to 4K
