Well, every game that runs at higher than 1080p on PS4 Pro is super-sampled down to 1080p on a 1080p tv/monitor. This results in a cleaner image than you would get playing the same game on a normal PS4 or PS4 Slim. It's basically like extra anti-aliasing. Additionally, certain games offer other improvements on Pro, a few offer high detail modes, which enable higher end settings from the PC versions of the same game instead of higher resolution, a few offer higher framerate modes (though very few games have high framerate modes that actually hit 60 fps), a few have minor upgrades like improved shadows or textures over the standard PS4.
Is there any settings I should be aware of? I've turned on boost mode. Thanks for the info, btw. I'm going to compare games side by side to see if there is a diff.
On a per game basis, some games have a choice between resolution mode and framerate mode, and fewer still have a choice between resolution, detail, and framerates modes, you have to pick those in the in-game options menu. Other than that you're good. Best way to compare the side by side difference is the digital foundry analysis for each game, they usually do a side by side between standard PS4 and PS4 Pro and between standard XB1 and XB1 X somewhere in each analysis video, if you watch their analysis video on a 1080p tv, it gives you a good idea of what the cleaner image quality produced by supersampling actually looks like. It is a noticeable difference to me personally, though not a huge difference.
Damn, I still don't understand. Every list is confusing the hell out of me. Do devs actually release info on what they do with pro enhanced games?
Alas, I'll just wait for the 4k TV.
Yeah, you're probably better off waiting. I'm willing to bet that Pro will be on sale for $330 or less on Black Friday, and you may even be able to nab the RDR2 Pro bundle for that price on Black Friday if you're lucky and stock lasts until black friday.
