All this talk about the graphics and always the critics ignore this part:
The damage was disabled in the demos, many basic effects were not implemented (skidmarks, sparks, backfires, good smoke and dirt, track shadows over the cars were missing, no wind effect in the grass, etc), they have not showcased yet anything about weather effects/tracks, nothing about the night tracks, etc.
The physics are fine confirmed by the people who played the demos and the differences are clearly seen in the one car replays, is just the multiplayer netcode like happened in GT5/6 that does not update the online cars at the same rate as the player own car physics or with the same variables, so the rest of online cars often jump postitions and appear to run with basic physics. In spectator mode that happens with all the cars but is not representative of the real inputs or the car behaviour experienced by the players. I hope it improves in the final game.
All this is basic stuff to anyone who played previous GTs.
Maybe they can implement an slider with a precise time selection, like in previous GTs but this time with no dynamic changes.
