Crysis 3 is a linear game... not an open world game... that kind of grass is mostly in just 1 part of 1 level in the entire game.... and that part ran like ass
Please, don't talk of things you clearly DON'T understand. Please, I beg you.
The things we are talking about have practically NO impact on the world being "open" or not. Moreover Cryengine is clearly built also to provide a full open sandbox world if the game is built for it.
GTA 5 .... no, just no.. watch some videos dude... it doesnt look better... it looks good, but not better
Listen, given your capability of understand what technically defines "grass looking good" in this instance, it doesn't surprise me that you cannot see how GTA V grass is much better. However that doesn't meant that it is not better, because it is, it just means that you don't know where to look at.
it looks great... i dont know why anyone would complain about that kind of quality
Proving the point.
You are clearly not able to judge what constitutes "good" grass in a game. Those shots have NOT good grass, both from an artistic and technical quality (ffs, distant grass looks cardboard given the mipmaps).
I understand you like the game and you feel the need to defend it at all costs, but please, at last have the humility of talking of subjects you have some knowledge about. It is not just a matter here of what you personally "like", there are technical and objective parameters to judge the thing.
The grass in W3 seems like a painting of an impressionist like Renoir, not real (as in real life) grass. Shadows are practically absent (they are present only if coming from a secondary source. it's not present in-between individual instances of the grass, and those shots, especially the second, demonstrate it clearly), the lightning is clearly fake (it is always lighten the grass from the same direction, no matter the side of the grass that should be really illuminated), the foliage is too blurred and lacks definition (to compensate in those shots there's a lot of sharpening, but that creates a lot of aliasing and accentuates the problematics of the light).
