If i cteate a game like uncharted 4 in unreal it looks better like in its game engine or uncharted engine is more powerful than unreal
I don’t think it’s actually a matter of engine. Naughty Dog (the studio that makes Uncharted) is in the same building that the makers of the proprietary engine for Sony are in. This gives them some access to the engine. Meaning they can probably push it to it’s limit.
Now this doesn’t actually change the way the game looks. It’s more the limitations of the that make the difference, it simply can’t render more than a certain amount. However if you would put in a lot of time and effort with a big team like Naughty Dog, I bet you can make a better looking game for PC.
TL;DR: It’s not only about the engine in this specific case, there’s a whole lot more to consider.
