The ps pro GPU is more powerful then the 1s so.
It's important to note that xbox 1s upscaling gives NO VISUAL ENHANCEMENTS TO IMAGE QUALITY. Upscaling ton4k is not an image enhancement and 1s can only upscale games in 1080....how many xbox one games are in 1080.......
Whereas ps pro has a new GPU that allows much better anti aliasing and ability to give higher resolutions. Basically a much better picture in comparison tof ps4 and 1s. You will see a visual difference.
Your ignorance of what upscaling means has you thinking 2 machines that both upscale mean they look the same
If you're that interested in watching 4k discs you should not buy an upscaler. You should buy a native 4k player. And if you say you won't buy a UHD player because it's not a cheapy in your console, you weren't that serious to begin with.
First off all stop trying to insult my intelligence. I obviously know what upscaling is and so you don't have to educate me on it. More importantly I obviously know that the PS4 Pro is vastly more powerful than the Xbox One S and so when a game on the PS4 Pro is upscaled to 4K its going to look better than a game on the Xbox One S upscaled to 4K. But its still upscaling nonetheless. Point is you said the Xbox One S can't do native 4K but neither can the PS4 Pro. So I don't understand why you pointed that out.
