In fairness, their first trailers for the past 2 GTA games haven’t been gameplay, so I assume they’re just keeping with that pattern. And also those trailers did look similar to the final game, not exact but I don’t think it’s much of a stretch to expect GTA VI to look this good on max settings.
Framerate on the other hand, maybe to look this good it’ll have to be 30 which won’t be nice
It’s the mocap/animations. Every character in every scene in the trailer is fully mocapped. Crowds dancing in sync together at a club, reacting to eachother on the beach, parking on a busy street and exiting cars. I’m sure some of it is in the game, in scripted encounters. Probably not random sandbox gameplay people think of when they think GTA
