Whole argument about needing dynamic GI is due to not being able to bake lighting on 10x10 kilometers and you suggest to compare with lightmass? 
That’s Kingdom Come: Deliverance and that map is actually big with lots of objects. But there’s some on/off test on trees if that’s what you want to see.

Why am I posting these? just watch the video. https://youtube.com/watch?v=DctiRSFwoiIAnd again, that’s old, SVOGI was still an experimental feature in cryengine running on older hardware.
I think part of the reason some of you guys oppose dynamic GI despite the fact that it makes games look better is (as you guys mentioned) that you think the effort and money is better spent on other useful features. That the money and man-hours spent on dynamic GI is a waste. But look on the other end, the money and man-hours are being spent on RTX instead.
Would you have been happier to have a working dynamic GI solution even if it cost you 15 FPS or have RTX that has nothing to do with game development? because that’s what you’re going to get.
But if you’re coming from the perspective that you prefer them give you more smaller useful things than one big dynamic GI, well people have been crying for spline decals for years and -0- is the amount of attention they received from Epic. That’s a trivial thing to do for Epic. Man we’re still trying to figure out how to use/fix the “New Physically Based Lighting” that is shipped with 4.19 and they’re not even responding to the posts regarding that being broken right after having released it to the public.
I’m not sure where you guys are truly coming from but hey, eventually UE4 will lose it’s popularity when it comes to making games because making games isn’t what Epic is developing UE4 for, they’ve been developing a GDC open world hype-only engine, a car showroom engine, a Paragon engine and now a Fortnite engine without taking others into account. I’ve seen the exact same situation with Crytek before their engine lost popularity. They made cryengine a Crysis engine instead of a game engine and everybody knows that. Now they’re posting articles on 80.lv and trying to pull people back but they can’t.
Basically instead of giving you a lego kit to make things with it, they’re making a lego thing using a few pieces, and allowing you to disassemble and reassemble that as much as you want. When the entire additions you get to the engine are from what’s been used in their internal games,you’re constantly limited to make games within the limits of their internal games. That’s not why people sign up here.
Time will make things right. But it’s going to cost a lot.
