And especially for the things that there are potentially thousands of on screen. And especially for things that are semi complex models. And especially for things that are small at a distance....
Yup, I'm no pro game dev, and even in my hobby projects I deal with it at the start of development. It's really easy for character models like this because you do it once for one model and tell the artists (also me) the resolutions for the textures. Then in early development, you use one model for everything while the artists make more variety.
It's not something any decent dev would leave for later.
I'm guessing they haven't tuned the multithreading code and they're getting a lot of lock contention. That's a much harder problem to solve than LODs or other low hanging fruit. You can turn around LODs in a week, multithreading issues can take months.
I see a shitton of misinformation on the CS subreddit - teeth post, "the economy is a lie" post. There's basically no reason to trust people outrage baiting, regardless of whether they are right or not. We know the game's not finished, pointing out obvious bugs is just beating a dead horse. In four months we'll be several patches deep and all of this will be moot.
Not only wait for the reviews, but wait for the hype to die down a little.
When Destiny 2 released, the entire playerbase was super positive about it - it fixed everything that was wrong with the first game, they said. After a couple of weeks, some players started mentioning there was no real endgame, nothing to chase because of the fixed loot rolls, etc, and that they felt "done" with the game after 80 hours or so. Everyone else told them to shut up, obviously they were burnt out after playing 80 hours in two or three weeks. And then a couple of weeks later, everyone else started to hit the same point - they had their perfect gear already, they'd done all the content, there was nothing left to see.
Watching a game go from incredibly positive reception to a fairly jaded, luke-warm-at-best reception over the course of ~5 weeks with nothing about the game changing was quite something. And it basically showed me I should wait a few months at minimum for hype to die down and the opinions to settle before I think about buying a game. That said, I'm a patient gamer anyway and usually wait far longer than that anyway, but yeah, I think Destiny 2 perfectly illustrates why you should wait longer for a community consensus.
