This kind of stuff has generally been the norm for me too ever since odyssey released. Minecraft textures popping in and out throughout approach to a planet. Sometimes bits and pieces of the surface resolve nicely at certain distances, sometimes it all stays ugly until touchdown; every once in a while things look like they should look all the way through approach to landing, but it’s rare.
It’s the kind of thing where if you want to take a good screenshot, there are usually individual moments where everything looks good, but the overall minute to minute experience is one of shifting changing surfaces and visual artifact mess.
I’ve had problems with Horizons’ planet rendering from time to time, but they were the exception rather than the rule, and on the whole looked great at every stage without tiling or awkward distracting transitions. Odyssey still hasn’t fared so well even after the revisions and updates.
Seems like the only people who even have a chance of non-buggy graphics are folks who have machines well in excess of recommended specs, with every setting turned to the max, and even then it’s a bit of a coin toss.
