Whoa, somebody changed the config settings and created a map to showcase the graphics fidelity that the engine is capable of? You're right, that totally disqualifies it, it might as well be pre-rendered and photoshopped.
Edit: Eh sorry for the unnecessary snark, but come on, what a weird aggressively pedantic response that was.
I'm the one being aggressive here? Like what? I wasn't even responding to you in that post.
Point is, it's not what the game looks like at stock settings OR during any level. If you are going to talk about how the game looks with modded cvars and custom maps because "the engine is capable of it" then that's fine but it does not mean this is how the game will look if you were to load up a random mission from Crysis and turn up the settings to V. high the game. The config settings has pretty big effect on the graphics and it's not just "some config settings" considering just how much you can change in the cvars.
Most if not all games can do a lot more than what you see because the engine is capable of doing a lot more. It's just that those games won't allow you to change configs as much as Crysis. As such we have to draw a baseline when comparing one technology a to another and that baseline is stock engine with stock settings. For example, Uncharted 4 has issues with its shadows and motion blur but I'm sure the engine is capable of having better implementation of those, but that does not mean we can't say that the implementation as seen in the base game is poor. Or how about downsampled shots for games? At the end of the day the engine is capable of doing that but you won't pass it off as an accurate representation of what the game is like now would you?
And please read my post again, especially this part. Nothing you say is something that I already didn't mention in my post.
You can make an argument that at the end of the day it's still using stock engine but I'm pretty sure if people had tools to make maps for other games those games too would end up with maps that are more detailed than base game. Still it does not discount the fact that it's using modded cvars.
