@JennyB_010 Fundamentally the game does not look good for a few pretty simple and obvious reasons - it had a very troubled development in the middle of Covid, was likely rushed, it's unoptimized, and with all of the refunds EA most likely did not want to have as many people working on the game after release.
The game looks better now than it did at launch - because the big maps were shrunken down and there's more things around. However it's still extremely CPU bound. If the game doesn't run well, the priority will be to get it to run at a playable framerate, not to make it look pretty. The devs have stated they're working with a hard limit on how many objects they can have in maps.
Distribution of clutter is the main reason why the game looks worse. On a technical level it is superior to BFV - the dynamic weather also includes dynamic lighting over the entire map at a scale that has not happened in past BF games. The textures are higher resolution than BFV. (Dynamic) Explosions are probably the best in any game. However the game is low on clutter. A lot of indoor areas players hang around are absolute liminal spaces. You can see some screenshots illustrating this in this older post. It was even worse at launch.
The game isn't just on the PS5, it is also on the PS4, Xbone, XSX, XSS, PC. You're probably conflating something with the PS3, the last notable console to be hard to develop for. Or misunderstood something, like how the SSD (revolutionary 10+ years old technology) makes it so devs don't have to do wacky stuff like make copies of the same assets for faster loading? This isn't something that would make it massively easier to make a game.
People also love to repeat a bunch of meaningless if not completely incorrect things. Keeping the seagulls lowpoly is the correct thing for DICE to do.
