That these videos have become so hard to discern any difference at all at times feels like we've abandoned marketing towards any feature a reasonable consumer might care or even notice for exclusively tribal chest thumping.
Forget the early promotional videos, they show scenes that are still under development and with incomplete tech, but when the games come out the differences become clear as night and day.
This shot here from Black Myth Wukong (timestamped) demonstrates the massive difference between RT off vs RT on, with RT on it's like the lights are on in the scene, with global illumination bouncing off the ground onto the trees and mountains, extending far into the distance vs no proper bounce or distance illumination whatsoever in the RT off shot, that's a next gen difference right there.
Or this gameplay clip from Black State, without RT reflections the scene would be full of screen space artifacts and hacky looking reflections (with improper shading and geometry details).
but I was speaking specifically to the Black State trailer
Well, it's too early for Black State, the RTX integration is fresh, who knows what will it develop into in the future, Black Myth offered nothing more than DLSS and some limited RT on UE4 upon it's announcement, then it developed into full fledged path tracing. Black State could be heading into a similar direction.
Sure, I'm just noting that I think the bit that gets a bit silly is when they use it to advertise a feature that is just... in the game/engine and has nothing specifically to do with them
In the early days of ray tracing, when NVIDIA had complete monopoly over it, NVIDIA marketed lots and lots of UE4 ray traced games, that used UE4 stock ray tracing options, NVIDIA engineers were on the ground helping devs implement the tech. I guess that gave them the right to market it with their brand.
In the case of Black State, we don't know If the developer is using the NVRTX branch of UE5, if they were then I guess NVIDIA has the right to market it.
For example, the developers of Retrieval are using RTXDI for their UE5 horror game, which comes only with the NVRTX branch, apparently several developers are using it right now to make games, the use of the NVRTX branch in the wild is bigger than some have previously thought.
